I have a very regular menstrual cycle-every 22 or 23 days i get my period. I am curious on why I'm feeling menstrual like dull cramps when my period has been over for a few days now. I had unprotected sex with my Husband Oct 28th &29th and got my period October 30th. I know what ovulation cramps feel like but these are different. Given the timeline, could pregnancy be an option?
