Week 20: Oh Boy...or Girl

You've got a heavyweight in your belly now (well, in baby terms, anyway). Your little champ weighs about ten ounces and has a height, crown to rump, of about six and a half inches. Think small cantaloupe (and probably as sweet too).
You've got a heavyweight in your belly now (well, in baby terms, anyway). Your little champ weighs about ten ounces and has a height, crown to rump, of about six and a half inches. Think small cantaloupe (and probably as sweet too).

Is it a boy cantaloupe or a girl cantaloupe? If you're carrying a girl fetus, her uterus is fully formed this week and her vaginal canal is starting its development (which means that in about twenty-five or thirty-some-odd years, she could be just where you're at, Grandma!). She also has primitive eggs in her tiny little ovaries now, seven million of them — though by the time she's born, that number will be down to two million (still more than she could ever hope to use). And interestingly, your baby girl will be born with all the eggs she'll ever have.

Have you got male? If your fetus is a boy, his testicles have begun their descent this week, though they're still located in the abdomen, waiting for the scrotum to finish growing so they'll have a place to drop into in a few weeks.

Though the external genitals in both male and female fetuses still have a way to grow, you should be able to find out the sex of your baby (if you want to) during an ultrasound exam.


Effects on Mommy: Good Hair (and Nail) Days

You can credit (or blame) those pregnancy hormones again for changes in your hair and nails. The increased blood circulation that's bringing more nutrients to them also deserves some thanks.
Congratulations, you're at the midpoint of your pregnancy. Keeping pace, your fast-ballooning uterus has also reached the midway point, just about even with your belly button now. So go ahead — take a feel. That's one of the perks of being pregnant — you get to rub your belly anytime you want (in fact, it's expected when you're expecting). Happily, there are other perks of pregnancy too. Can't think of any? Well, here's one: Have you checked out your nails lately? They're likely growing faster than usual, and faster than you can manicure them. What about your hair? Does it feel thicker and look more healthy than usual? It's probably growing faster, too (not to mention growing in unexpected places, which may not be such a good thing). You can credit (or blame) those pregnancy hormones again for these changes. The increased blood circulation that's bringing more nutrients to your hair and nails also deserves some thanks.

The hair and nail changes are temporary…once again, good and bad news. Because even though your nails might be long, they can also turn dry and brittle (of course, it's those pregnancy hormones). And though you may love your lavish locks now, don't get too attached to them. Your good-hair-day run ends with delivery — when the normal daily hair loss that's suppressed during pregnancy (thus the thicker hair) resumes with a vengeance. Once the baby is born, all that hair that didn't fall out during pregnancy will — making you wonder whether you'll need to reach for the Rogaine (don't worry, you won't).
