Cramping after pap smear

I had scheduled a dr visit today bc I've been ttc for almost two mos and af hasn't arrived. I've been having very mild cramping sporadically the last week or so with no period. After a negative pt, I had a pap. Now I'm having stronger cramps. Wondering if it could be from the pap or af? Thoughts? I know time will tell, but I don't remember this feeling from my last pap.
