3 Weeks Pregnant

Fetal development in week 3

Most women are still completely unaware that their body has been hi-jacked by a tiny life-form despite the many wildly dynamic changes taking place inside of them.

Just imagine, your tiny baby is now about the size of sesame seed! Which is massive growth considering that they were but a microscopic pack of cells just two weeks ago.

Even more impressive, your seed baby is now composed of three complex "germ" layers: the ectoderm, endoderm and mesoderm, which is just a fancy name for what will one day be your baby's nervous system, vital organs, and skeleton, respectively.

In terms of their looks, your uterus squatter looks something like a very tiny pear, where the round part of the pear will become their head and the pointy part will become their spine.

Undoubtedly the most exciting development of this week is somewhere around the 21st day, when your pear-baby's heart will start to beat! Still, the heart chambers and valves will not be fully developed until approximately 8 weeks.

And how's mom doing?

You're probably still on the same lame symptom train as last week: fatigue, swollen breasts and frequent urination, which is totally normal... as is trading symptoms or losing them.Calcium is an extremely essential vitamin during pregnancy, which your body will strip from your bones to give to your baby if you don’t have enough existing calcium in your system.

If you're lactose intolerant, a practicing vegan or vegetarian, or have a history of substance abuse, chronic disease, or the minority who are expecting twins (or more!), you are in even higher need of a healthy diet and prenatal vitamins to fend off the nutrient deficiencies you're going to be prone to in your pregnancy.

Calcium is an extremely essential vitamin during pregnancy, which your body will strip from your bones to give to your baby if you don't have enough existing calcium in your system. This is also a critical reason older women are so much more prone to osteoporosis: they simply didn't get enough calcium during their child-bearing years.

Some great calcium-rich foods for pregnancy include: plain yogurt, cabbage, sardines (really!), white beans, bok choy, almonds, cottage cheese, and tofu.

If you have a kitty (or more), it's time to start having someone else changing the litter for you. Avoiding this chore will prevent you from the remote chance of contracting Toxoplasmosis. Toxo is a parasite that is only very rarely found in fecal matter of vermin and rodent-eating felines. Don't worry though, you don't have to get rid of your cat. Also, make sure you fully cook all your meat, wash your fruits and veggies clean, keep away from cat litter and wear gloves if you're going to work with any soil.

Did You Know?

Early on in pregnancy, the hormone Relaxin fills your system, leading to hyper-flexibility in your joints and muscles. Relaxin facilitates the stretching of your uterus and repositioning of the pelvic floor. As a result of this added flexibility, it is common for pregnant women to strain muscles and ligaments. Stretch carefully during your exercise routine!
