Ok ladies (may be tmi)

Brenna
Ok so my fiance and I were having intercourse and I was on top. I just got on top and had a sharp pain in my butt. Never happened to me before. The sharp pain was hurting so bad we had to stop. So i layed down in bed and I get the sharp pain on my waist and still on my butt. Is this normal? Has it happened to anyone else?
