in pregnancy, especially if you're drinking as much water as you should. It does lighten up some in the second trimester as your uterus moves up high enough to stop squashing your bladder, but I'm told it gets bad again third trimester as it expands big enough to do it again.
Yeah it was bad the first trimester. I'm in the second trimester now, and I only have to get up once. "Only." I've read that if it's really interrupting your sleep, you should try to drink a lot during the day and then limit your liquid consumption late at night.
It varies for me :) I am 22w2d and one night I will pee once and the next night I am up 4-5 times. And other times I feel like I have to pee soooo bad and only go a little. Little boy must be sitting on my bladder :)
