Mid cycle cramping, not usual for me

Ha

I am eight weeks postpartum and had my first period already. I am on cycle day 15 and got a positive ovulation test yesterday. I had intercourse with my spouse before my period, we used the pull out method which I know isn’t 100% effective. I am having really bad cramps today, and I don’t remember having cramps midcycle before I had my baby. Is it normal to get cramps during ovulation or after ovulation? Or could this be a potential pregnancy?
