1 Week Pregnant

Fetal development in week 1

It's been a momentous past couple of days - even if you don't know it yet.

At some point roughly 1.5-3.5 million sperms took aim at your fallopian tubes and one superior little seed hit the target spot on. The now-fertilized egg is currently in one of your fallopian tubes merging with the sperm to become a zygote, where cell division is occuring at an incredibly rapid rate.

Your little zygote will spend the next 7-10 days dividing and growing as they travel down to your uterus, where they'll nestle into your cozy blood-rich uterine wall.

The implantation process may result in a little spotting for some women, which is caused by the sloughing off of uterine wall at the implantation site. This is perfectly natural and not a cause for concern. When your little zygote is finally implanted, it is officially considered a "blastocyst" measuring about 0.1-0.2 mm.

Long story short: this week is the beginning of your child's life.

And how's mom doing?

Your body can already sense the presence of your microscopic bean-baby and has begun producing Early Pregnancy Factor (EPF) protein, an immunosuppressant which prevents your body from rejecting your growing zygote. What's more, you'll continue to produce estrogen and progesterone thereby suppressing ovulation.

You won't express any other of the main symptoms of pregnancy at this point, but soon your hormones will be fluctuating more intensely than any other time in your life.

So yeah, you won't be feel nauseous this early in the ball-game, but get ready: soon your hormones will be fluctuating more intensely than anything you've experienced before and you and everyone close to you will be noticing.

If you've been planning this pregnancy by monitoring your morning basal body temperature, you will see that your temperature remains elevated beyond day 16 of your Luteal Phase (post ovulation). This will be the first verifiable sign that you're pregnant!

Did You Know?

The Center for Disease Control estimates that if every woman of child-bearing age consumed 400 micrograms of vitamin B folic acid daily for at least a month before conception, there would be a 50% decrease in the number of babies born with neural tube defects (spinal cord disorders such as spina bifida and anencephaly).

The Trying Game

I’ve always felt kind of weird when someone told me they were “trying” to have a baby. To me, informing someone about the purpose of your bedroom activities is a major no-no.

I don’t mind thinking about babies, or even the desire to have one. But for some reason, the second someone tells me she is going “off the Pill” to “start trying,” well, I freeze up.

Babies are sweet. Pregnancy is beautiful. How you get pregnant? Well, there’s an entire film industry devoted to that process.

I’m a visual person with an active imagination. It doesn’t matter how you put it, my mind will go there. For the longest time I couldn’t help but snicker when I saw a pregnant lady walking down the street.

So let’s just say I’m always surprised when people tell their parents of their plans. “Hey Mom, sorry we can’t stay for dessert. We’re trying for a baby and I have a can of whipped cream in the fridge with my name on it.”
