You've got a heavyweight in your belly at 20 weeks pregnant well, in baby terms, anyway. While your baby is definitely getting bigger, there's still plenty of growing room in there, which allows him to twist and turn and allows you to feel his acrobatics!
Curious about whether that melon-sized belly has a boy or a girl inside? Now's your chance to take a peek! Though the external genitals in both male and female fetuses still have a way to grow, you'll be able to find out your baby's sex via the second trimester ultrasound, also known as the anatomy scan , usually scheduled for anytime between 18 and 22 weeks. You'll also get a detailed sneak peek at baby's other major organs and measurements and make sure your little one is developing normally.
This exam, which is much longer than the routine ultrasounds you get at your doctor's office, gives your practitioner a chance to see how things are going in there — and wow, are they going!

But even though your nails might be long, they can also turn dry and brittle. And though you may love your lavish locks now, don't get too attached: Your good-hair-day run ends with delivery, when the normal daily hair loss that's suppressed during pregnancy thus the thicker mane picks up where it left off and then some.
Are you in the Hunger Zone? With weeks of nausea and food aversions behind you, you may be more than ready to make up for lost eating time — move over crackers, hello four-course meals! But before you dig into that all-you-can-eat buffet at lunchtime, here's something you might want to consider. The grazing approach that was your mealtime MO during those queasy months is still the best way to feed yourself and your baby now that food's no longer a four-letter word.
Not only does it help fend off pesky second-trimester tummy troubles, like the heartburn and indigestion that are sure to set in by your second trip to the buffet, but it also ensures that baby's getting a steady supply of calories when she needs it the most. In fact, studies show that moms who eat at least five small meals and snacks a day are more likely to carry to term.
So bring on the grub when pregnancy hunger hits, and lots of it — just bring it on a little at a time. Remember that there is no right or wrong decision. It's completely personal — up to you and your partner if you have one. Also remember that even if you do find out the sex of the baby during your ultrasound, sonographers have been known to be wrong — so you'll still need to be at least a little bit prepared for a surprise.
First-time parent? You may think the subtle motions are butterflies, gas or a grumbling tummy, however. Of course you should embrace your growing belly — and look at those extra pounds as a wonderful sign of the miracle happening inside you.
But that doesn't mean you should eat as much as you want of anything you want. Thank you for sharing our content.
