Wtf is going on with me? (Sorry if this is TMI)

K
I need help. I get these really sharp pains right below my belly button all the way down which is like a few inches to where the hair grows on my vagina. This doesn't happen a lot. Not even everyday. Just every once in a while. I'm not on my period and I am sexually active but I haven't been for a few days and I always use protection. The condom has never broken. So does anyone know what these sharp pains are? Or ever experienced them?
