You still have 30 weeks of pregnancy, but your little one already seems to be prepping his or her appearance with the development of tiny fingernails and hair! Not only that, but your baby is beginning to form teeth under his or her gums—and the first of those won't even appear until your baby is at least four to six months old! In other big news this week, you'll be excited to learn that tiny versions of all of your baby's vital organs have fully developed and are starting to function.

Well, Hello, Belly!

Yours might be starting to swell a bit, although no one is going to suspect you're pregnant yet from your physical appearance. As your abdomen muscles and ligaments stretch to accommodate your growing uterus—now the size of a grapefruit!—you might feel some aches and pains known as "round ligament pain." You've also probably noticed a network of blue veins criss-crossing your belly and your breasts; as your body increases its blood volume to support your baby, it also needs to increase the "roads" that carry that life-giving liquid!

Tip: Help for Both Ends

Some moms get constipated from the pregnancy hormones. Drink a lot of water and try to boost the fiber in your diet to keep things moving along. You might also be suffering from pregnancy-induced headaches (these can be caused by stress, hunger, exhaustion, and/or dehydration). Be sure to check with your doctor before you take any over-the-counter headache medications. It's likely your OB will green-light acetaminophen but recommend you stay away from ibuprofen.
