This has been going on for about a month now, but im 35 weeks and a day and through out the night i wake up to pee alot. Well somwtimes i get a very sharp pain in my lower stomach on my right side, but its only when i straighten my leg fully. I then have to lay in bed for a minute or two to let the pain go away. It only happens when i have to pee though, and only at night. Could it be from being curled up and stretching my leg to fast, or how the baby is laying on my bladder? Also i dont think i have a uti because i just went to the doctors Tuesday and they didnt say anything about a uti.
