Helppp!

I’m 33 weeks pregnant with my first child and I’m experiencing sharp pains in my vagina it’s pretty uncomfortable to the point where I can’t move but it only last like a couple of seconds.. and yes I know it’s my vagina doing it and not my stomach.. has anyone else experienced that what is this it’s kinda embarrassing at work I literally have to stop what I’m doing for a couple of seconds because I can’t move. Somebody please help me 🤦🏾‍♀️ it just happened again i was kinda worried if it was a sign of labor or not 🤔
