For a lot of women, morning sickness is something that they believe can be conquered in the first few months of pregnancy, never to return to again. While this is true for some women, there are quite a few early pregnancy symptoms that seem to show up again once a woman hits her third trimester.

Welcome back those sleepless nights filled with nausea and constant trips to the bathroom to pee.

As uncomfortable as those first few months of pregnancy may have been, the hope that things would get better soon usually kept women going. While I hate to be the bearer of bad news, it’s important for women to realize that early pregnancy symptoms can return at any time throughout their gestation. Of course, once a woman hits the third trimester the hope and excitement of meeting her baby soon will also become a light at the end of the tunnel.

Again, every woman and every pregnancy is different. There is a chance that some symptoms could return worse than they were before and others might be milder. The key is to embrace and appreciate those moments of pregnancy when you feel amazing because they might not last. As for the symptoms themselves, there are quite a few things to look out for. Here are 15 first trimester pregnancy symptoms that can show up again in the third.

15 Please, Not This!

Nausea is a very common early pregnancy symptom. It usually occurs in the first trimester for most women and is sometimes what signals to a woman that she may be pregnant. According to Pregnancy.lovetoknow.com, the first trimester is usually the worst for a lot of women because of nausea they experience. A woman’s body goes through a lot of changes in the very early stages of pregnancy and those hormones cause nausea for about 90% of women. Of course, this nausea is usually expected to go away after you are 12 or 13 weeks along.

Some unlucky women actually stay nauseous throughout their entire pregnancy, and other women have nausea come back around the time they are entering their third trimester.

For most women, nausea late in pregnancy should not be a cause for concern. But, the idea of morning sickness coming back may be concerning enough.

However, if women experience third-trimester nausea that is severe and causes them not to be able to eat or drink, it is important for them to seek medical attention immediately. Some pregnancy symptoms in the early stages become more extreme if they are experienced in the third trimester, so it is important to be aware of what is safe and what isn’t.

14 Down With The Sickness

Vomiting is never fun, but in the first trimester of pregnancy, it is often times very normal. According to Mom.me, as many as 33% of pregnant women vomit during pregnancy. Studies show that women who experience morning sickness are less likely to experience miscarriage or preterm delivery. This is an incredible thing and makes the morning sickness completely worth it.

However, it still doesn’t mean that vomiting too much is healthy. If a woman has severe vomiting, it may be a sign that abnormal placenta growth is occurring, or that something is wrong with your baby. Vomiting is usually taken a little more seriously if it occurs later in the pregnancy.

If vomiting occurs during the third trimester as well as the first, it could simply be an extension of the previous morning sickness, since hormone levels are constantly changing throughout pregnancy. If you never experienced nausea or vomiting in the first trimester, third-trimester vomiting could be way more serious. Excessive vomiting can lead to dehydration which is dangerous for the mother and her baby so it’s important to contact your doctor or midwife if this one persists. It’s advised to always drink enough water and keep your doctor informed on how often you are getting sick, even if it was determined that nothing serious was going on.

13 Is It Bedtime Yet?

The constant desire to crawl into bed and sleep is a very normal symptom of pregnancy. Growing a baby takes a lot out of a woman, and getting a little extra rest never hurt anyone. The extent of this tiredness seems to vary among women, but according to American Pregnancy, most women feel more tired than normal when they are pregnant. Some women feel exhausted throughout their entire pregnancy, while other women actually feel pretty good and seem to enjoy their changing body. Whichever boat you fall in, it’s common for the tiredness to occur during the first trimester in the early stages of pregnancy and then return in the third trimester.

Many women are lucky and get the second trimester off.

That is usually where they hit their stride and finally feel like they’ve conquered the constant waves of sleepiness that they experienced early on.

However, the third trimester is right around the corner and this symptom almost always comes running back. Fortunately, there are a lot of symptoms that are far worse than being tired, but for a busy mom-to-be, the third-trimester exhaustion can really kick her butt. The increased progesterone levels are responsible for making you sleepy, and the physical and emotional changes that occur at the beginning and end of pregnancy can also lead to decreased energy.

12 The A/C Needs To Be Freezin'!

According to BabyCenter, it is totally normal to have hot flashes during pregnancy and more than one-third of women experience them. Fluctuating hormone levels and increased metabolism can cause the surges of heat that many women feel during pregnancy. Hot flashes during pregnancy can apparently last from seconds to minutes and usually affect the head, neck, and chest.

The lowering hormone levels particularly drop in estrogen, usually cause pregnant women to have their hot flashes get worse as their pregnancy progresses.

By the second trimester, hot flashes are a common occurrence but they get even worse during the third trimester and can even continue after the baby is born if the mother continues to breastfeed.

It is very important for pregnant women to determine the difference between hot flashes and a fever. While hot flashes are a totally normal symptom of pregnancy, a fever can be dangerous. Fevers can signal an infection and high fevers are even more dangerous during pregnancy. If a fever breaks 100 degrees, it is advised to contact your doctor. Treating the simple hot flashes can be done through drinking ice water, opening a window, or using a fan. And, as always, remember that these hot flashes will eventually pass just like the other pregnancy symptoms.

11 Quit Making The Room Spin

According to Vertigo Treatment, dizziness in pregnancy is not necessarily a reason to panic, but it’s also not something that should be ignored. Spells of dizziness usually occur in pregnant women in the first trimester, when their body is still adapting to all the new changes. In the early stages, a woman’s body might not have enough blood to support a growing circulatory system, which could cause some vertigo or dizziness.

Extra hormones cause blood vessels to widen, which sends more blood to your baby, but it also causes that blood to take longer to get back to you.

In the later stages of pregnancy, dizziness can return because your growing uterus is putting pressure on your blood vessels.

In the third trimester of pregnancy, dizziness can occur simply by lying on your back. This causes your baby to put pressure on the vein that carries blood from your lower body to your heart. Other reasons that dizziness could return near the end of a pregnancy is excessive heat.

It’s important not to sit in a stuffy room, or wear tight, warm clothes that your body can’t handle. If the dizziness gets the point where you feel like you’re going to pass out or you actually do pass out, talk to your doctor to ensure the health of you and your baby.

10 Just Need 2 Minutes

Fatigue is a pregnancy symptom that usually goes hand in hand with tiredness. While being sleepy all the time is one thing, fatigue takes a much harder toll on your entire body. According to American Pregnancy, fatigue is a very common symptom in early pregnancy and is most common in the first trimester. The fatigue usually subsides in the second trimester and returns in the third. During early pregnancy, the hormone changes are likely what causes the fatigue.

The second trimester is often called “the happy trimester” because that is when energy levels increase and women begin to feel like themselves again. Many women use this to their advantage and get a lot done because they know fatigue in the third trimester will come back even stronger. At this point in pregnancy, the extra baby weight and trouble resting simply add to the uncomfortableness. And, while fatigue often makes you want to do nothing, a little bit of light exercise might actually help.

Your emotions also play a huge part of your physical health. So whether the baby was planned or unplanned, it’s not uncommon for women to feel stressed and anxious about her pregnancy, the health of her baby, and motherhood.

9 Curse That Burger

Heartburn is actually a very common complaint during pregnancy. However, it actually has nothing to do with the heart and is actually just a burning sensation in the middle of the chest.

According to American Pregnancy, heartburn occurs when the valve between the stomach and esophagus doesn’t prevent stomach acid from passing back into the esophagus. The pregnancy hormone progesterone causes this valve to relax which can increase the occurrence of heartburn. This is often the reason for heartburn during the first trimester of pregnancy.

During the third trimester, heartburn is likely to return because of the growing uterus.

It puts pressure on the woman’s intestines and stomach. The pressure can also push things back up into the esophagus and cause heartburn as well. In order to try and avoid heartburn, pregnant women are advised to eat 6 smaller meals throughout the day, instead of three larger meals. They should also try and avoid fatty or greasy foods, and wait an hour after eating before lying down. If the heartburn becomes too severe there are natural remedies that a woman can try, but if those don’t work a medical professional can prescribe something that is safe to take while pregnant.

8 Never Enough Pillows

Most women know that they will hardly get any sleep once their baby is actually born, but it is very common to experience sleep problems during early stages of pregnancy as well. While many women feel very tired in the first trimester of pregnancy, the quality of sleep that they get is extremely poor. That tiredness and exhaustion from the day can translate over to the night and cause insomnia. According to Healthline, any pregnant women have a difficult time falling asleep and staying asleep. And, while this can occur in all stages of pregnancy, it is most common in the first and third trimesters.

On top of all this, by the third trimester when pregnancy is nearing an end, many women find it difficult just to get comfortable enough to sleep well. With a giant baby belly pressing on your stomach and bladder you will feel like you always have to get up and pee. Your nausea might have returned, your back and legs will likely ache. You will probably feel overheated as well which can make it nearly impossible to sleep. The overall sense of uncomfortableness seems to really show up in the third trimester, which is unfortunate because that’s when moms-to-be should be resting up the most since their little one will be arriving soon.

7 Middle Of The Night Troubles

According to Thebump, leg cramps are very common during pregnancy and usually signify two things. Either the mom-to-be is lacking nutrients, or she is dehydrated. These muscle contractions happen when your body does not have enough water or sodium. In the early stages of pregnancy, these cramps can be taken care of by drinking 8 to 12 glasses of water a day.

It’s also important to monitor your diet and make sure you are eating enough calcium, potassium or magnesium since a lack of all of these things can lead to muscle spasms. Now that you are pregnant, your requirements for these vitamins and minerals go up.

As the pregnancy progresses, leg cramps actually become more painful in the third trimester.

Many women may feel like they conquered this issue in the early stages of pregnancy, but they are not out of the woods yet. In the third trimester, your legs are carrying a lot more weight than they are used to.

So even if a pregnant woman is eating and drinking right, sometimes these leg cramps are an unavoidable recurrence in the third trimester. Stretching is one suggested way to ease some of the pain since it will keep your muscles more elastic and make them less likely to contract. Walking around and getting your blood flowing might also help.

6 Yoga Ain't Helping

According to KidSpot, “many women experience bloating, mild cramping and slight backache as a pre-menstrual physical symptom, and the same thing happens in early pregnancy as the uterus grows.” Backaches are one of the very common, yet unfortunate symptoms of pregnancy that occur in most women.

In the early stages of pregnancy, a woman’s body is going through a lot of changes. Some of these changes are hormonal, and some are physical. Once a woman conceives, her posture and torso are completely thrown off as the baby continues to grow. Many women can’t sleep on their stomachs or backs anymore because it makes them feel sick, and so sleeping on their side is unusual for them and causes them to get backaches.

As the pregnancy continues, these symptoms seem to only get worse, not better. The weight of the whom pulls on a woman's back while she lies down and sleeps. And, walking around constantly feels like she is wearing a backpack on her front. Once the third trimester hits, hormones also have a lot to do with this back pain. As a woman’s body gets ready for birth, ligaments and joints begin to loosen up to make delivery possible. This can cause backaches to be an early pregnancy symptom as well as a later one. And, about half of all pregnant women have this symptom.

5 Too Early For This

According to Parents.com, some abdominal pain during pregnancy is normal because of many reasons. Your organs are shifting, your uterus is expanding, ligaments are stretching, and some moms have pretty intense morning sickness. There could easily be a lot of reasons why abdominal pain during pregnancy exists.

And, while this pain is rarer and occasionally more serious, there are some harmless causes of abdominal pain during pregnancy. A growing uterus is one reason. It is advised to eat smaller meals, exercise regularly, and empty your bladder often because as your uterus grows it displaces your bowels.

Abdominal pain is a sign of early pregnancy, but in more serious cases it can be a sign of an ectopic pregnancy or even a miscarriage. In early pregnancy, miscarriage is always an option and something that should be considered. If the pain is harmless, the mother is not out of the woods just yet. There is a good chance this pain will come back in her third trimester and it might even be worse since her baby will be bigger. If the pain becomes really bad and the woman feels contractions before she is 37 weeks, she is advised to check in with her doctor just to be safe.

4 Get That Out Of Here

According to Healthline, food aversions during pregnancy are likely caused by the hormonal changes that are occurring. In early pregnancy, your hormone levels are rising rapidly and are most likely the reason that women have nausea, cravings, food aversions, and smell aversions. Unfortunately, for the women who feel like they can’t eat or smell anything without getting sick, this symptom is not something that always goes away after the first trimester. Your hormones will continue to affect your eating habits and appetite all the way through the third trimester.

While food and smell aversions are the most common in the first trimester they can actually change or come back at any point in pregnancy.

New food aversions can even develop later in pregnancy that wasn’t there earlier.

This is because it all depends on your changing hormone levels. In most cases, it is healthy for the woman to listen to her body during pregnancy. As long as she is getting the proper amount of protein and nutrients, she should be fine listening to her cravings and avoiding her aversions. One way women can make sure they are getting everything they need is by disguising the foods they are avoiding in foods that they still like, such as putting spinach in a fruit smoothie.

3 Need To Go Again & Again

Frequent urination is a symptom of pregnancy that occurs in the first and third trimesters. According to Kidspot, the reasoning behind this is due to the change in hormone levels during pregnancy which will increase your urine production as well your bodily fluids. While it may seem like there is no way around this, it is important for pregnant women not to limit the liquids they drink because staying hydrated during pregnancy is so important. If a pregnant woman really wants to reduce her trips to the bathroom she can avoid drinks that have a diuretic effect such as coffee, tea, and soft drinks.

Luckily, most women will experience some relief from this constant need to pee in the second trimester of her pregnancy. However, it is bound to return in the third trimester. In the last months of pregnancy, your baby drops lower in your pelvis to prepare for delivery. This puts a lot of extra pressure on your bladder and there are not many pregnant women can do to change it. If those middle of the night bathroom trips is really hindering your sleep, it is advised to drink less after 4 p.m. Make sure the required amount of water was already consumed before then.

2 But Can't Go #2

According to BabyCenter, constipation is a very common symptom during pregnancy and it occurs in around 50 percent of women. One of the reasons constipation can occur early in pregnancy is due to the increased levels of the hormone progesterone. Progesterone relaxes smooth muscles throughout the body, including a woman’s digestive track. This causes food to pass through more slowly. In later pregnancy, once a woman enters her third trimester, the pressure of a growing baby is not only on her uterus but her rectum as well. This can make it very difficult for a pregnant woman to go number two.

The most important thing is to listen to your body. If a pregnant woman feels the urge to go, she should not put it off. Making time for bathroom trips when they are needed will really help with constipation that could occur later in the day.

Since iron supplements can sometimes make constipation worse, it is advised to eat high fiber foods such as whole grains, rice, beans, and fresh fruits and vegetables daily. It is also encouraged to drink the recommended amount of water every day as well. Regular exercise also makes a big difference.

1 Overwhelmed By Everything

Whether this pregnancy was planned or not, there is no doubt that seeing that positive pregnancy test for the first time can be a little stressful. Even if you are extremely excited about this baby, the idea of everything that needs to be done and all the ways your life will change can cause some serious panic. Marchofdimes.org explains that even if all the new changes that come along with pregnancy are welcomed, it can still add new stresses to your life. While stress is a very common symptom of pregnancy, high levels of stress that continue for too long can cause health problems.

After the initial shock of pregnancy has worn off, and the woman has come to terms with her changing body and hormone levels, her stress might also decrease during the second trimester.

Stress almost always returns again in the third trimester. Not only is the arrival of your baby coming soon, but the stress surrounding labor and delivery can be getting really scary.

The discomfort, backaches, and mood swings can also cause an increase in stress. If the mom-to-be is still working, it can be extremely stressful dealing with her employer and trying to ensure her maternity leave goes smoothly. Some common ways to reduce stress is to eat healthily, exercise, get enough sleep and stay educated about childbirth. Planning ahead always reduces stress.
