Okay I woke up with this weird pain that goes all the way across my lower belly and and stays a dull ache until I stand up then it feels like tons of pressure and these awful sharp pains in my lower stomach and a dull ache in my lower back that gets worse when I pee. But it also feels like some major stretching in my stomach down there and its super tender when I feel it so idk what's going on... 16w2d with 2nd baby.
