New this week: Webbed fingers and toes are poking out from your baby's hands and feet, his eyelids practically cover his eyes, breathing tubes extend from his throat to the branches of his developing lungs, and his "tail" is just about gone. In his brain, nerve cells are branching out to connect with one another, forming primitive neural pathways. You may be daydreaming about your baby as one sex or the other, but the external genitals still haven't developed enough to reveal whether you're having a boy or a girl. Either way, your baby — about the size of a kidney bean — is constantly moving and shifting, though you still can't feel it.
How your life's changing:
You may notice that your bra is getting more snug. Soon you'll likely need a larger size with better support. Rising levels of hormones cause breast growth and other tissue changes, all in preparation for lactation. Your breasts may continue to grow throughout pregnancy. Don't be surprised if you go up a cup size or two, especially if it's your first baby. Keep this in mind, and allow for room to grow when investing in a new bra.
Feeling fatigued? Hormonal changes — in particular, a dramatic rise in progesterone — may be contributing to your sluggishness. Nausea and vomiting can certainly cost you energy, too. And you may be having trouble getting a good night's sleep at this point, especially if you're uncomfortable or find you need to get up to pee.
