Tmi question

Brooklynn • 23, married, mom to 2 wonderful boys, Mason and Tristan, and a 3rd boy is due July 9th, 2020.
Ftm here, lol, so All day yesterday I was having BH about every hour or so and several times I've had this really sharp pain shoot through my butt. Not my whole butt, my butthole... So weird, I know. Has anyone else had this? What was it? Also today I've been feeling crampy all over my stomach and the sharp butthole pain has been a constant if I move the wrong way. Any help is appreciated!
