Pain ..

Im currently 37 weeks 4 days.. I keep getting extremely sharp pains mid way between my vagina and my belly.. also in my vagina. They mostly come when I'm sitting with my legs crossed and I try and move but today they have been more frequent and just randomly come .. My next appointment isn't till tuesday. Any advice? Or can someone explain this too me?

Could be pain from dilating. Or just pregnancy pains. I wouldn't worry and just mention it to your doctor on tuesday.

It sounds like your cervix is pinching. Which usually means it's dilating a bit. Not much to worry about!
