Week 8: Goodbye sea creature, hello baby!
Fetal development in pregnancy week 8:
embryo in second month Woohoo! You've got one whole inch of baby inside of you! Your little embryo has finally reached the one-inch mark (30mm). And if it were possible to take a peek, you could actually see your tiny baby without a telescope! What’s more, your baby is finally starting to take on some very distinct human features. For starters, their little tail (really just the spinal cord) has disappeared completely. It’s nice to know your baby can no longer be mistaken for a sea creature! Additionally, both their toes and fingers are prominent with very little, if any, webbing. Upper and lower limbs all show recognizable joints (elbows and knees) and the lower limb bones are starting to ossify. But don’t expect your baby to resemble either parent quite yet. Right now, your baby’s head is disproportionately larger than the rest of their body--making up almost half of your little one’s height and weight!
And how's mom doing? Your slightly-larger-than-a-cherry embryo is also starting to have a physical impact on you this week—and not just hormonally, as you may be noticing a slight bulge at your midline-- mostly from water retention. Most people won't even notice the subtle change to your belly's shape, but since you’re if you have been extra moody lately, that may start to subside this week, as the placenta is beginning to take responsibility for your baby’s hormone production tuned in to every little change in your body, it hasn’t slipped past. Good news for the hormonally tortured: if you have been extra moody lately, that may start to subside this week, as the placenta is beginning to take responsibility for your baby’s hormone production. This means your body will soon be able to relax a bit from its over-production of hormones as the placenta starts to regulate your baby’s hormones-- allowing your body to focus on producing more normal levels of hormones for yourself (see Week 10).
