Pregnancy Week 31

You may be noticing more hip and lower-back pain. What gives? Pregnancy hormones are relaxing the ligaments and tendons throughout your pelvic area so that the bones can spread to make room for delivery. Your expanding uterus may also be putting some pressure on the sciatic nerve, which runs from your lower back to your buttock and hip area and down the back of each leg, triggering chronic tingling or numbness along its path—a condition called sciatica. But it's usually not serious, it won't affect the baby and it will likely become less intense as he shifts around in there.

Strangers on the subway reach out and touch your belly. A woman at the grocery store wrongly warns you against having sex ("It will make you go into early labor!"). Your neighbor asks if you're planning on circumcising your little boy (and clearly has strong opinions on the subject). Sound familiar? Now that your belly is front and center, chances are it'll attract a lot of attention and unwanted pregnancy advice. Just laugh it off and try not to let the comments worry or sway you. Your opinion and your doctor's are the only ones that matter; simply deem the rest amusing distractions.

At Week 31, you're probably finding your mind ever-­wandering back to the elephant in your third trimester room: how you're actually gonna birth this sucker. While the physical realities of having a baby are surely present on your mind, you're also bound to be curious about what goes on around you when you're giving it the ol' heave-­ho. Who do you let in the room with you? Will you really do something as horrific as poop in front of everybody? And will you even care? This week's podcast lets you in on the deepest darkest secrets of the delivery room, so you know just what to expect when you're done expecting.
