sharp stabbing pain in vagina..

Kelsi
So I've been having these random sharp pains that feels like they're right at the opening of my lady parts.. Lol it feels so weird. I'm 36 weeks so don't know if things are starting to happen or if it's normal. Anyone else have this? Sometimes it'll do it when I'm standing and I literally have to sit down because it's so uncomfortable. Also along with it sometimes feels like a stabbing in my bladder I guess? then goes away. Hard to tell the exact spot.
