Abdominal pain


I’m having period like cramps 4 days after my period ended in the lower, middle section of my stomach. I had sex last night could that possibly be why? I do get period cramps before my period every cycle but never this early. It’s been constant for 6+ hours. Nothing unbearable otherwise I’d be seeing a doctor.

Cycle history: 25 day cycle and I’m not supposed to ovulate until tomorrow at earliest. Last period was March 11-16 and next period is expected April 7th.
