So 36+5 weeks pregnant and I’ve been having s cramps on the top of my stomach and a lot of burning and pressure in my vagina since last night. I did go Black Friday shopping for a couple hours but it was no more walking then what I’m use to. They went away for a couple hours last night but have started to come back. They aren’t consistent, they just hurt. I’ve had Braxton Hicks before but they haven’t been this painful. Should I be concerned or is this normal?
