I usually have nights where I have to pee so often I want to die cuz every time I get up I have to stand there to chatch my balance before I can start walking.. But sometime (and it happens for a few nights in a row) where I don't have to go so much even if I drink a lot of water I think it's just her easing of my bladder :)
I had the same problem at 15 weeks because my little man was swimming in my bladder lol
I mean i'm 30 weeks & constantly go to the bathroom because my babies head stays on my bladder & it puts pressure on it . . .
Idk if thats normal at 12 weeks .
