Ive always had a period that lasted 3-4 days but with no cramping. I recently had my period on Friday aug 10th. It was very heavy and I was cramping bad. My period ended Sunday Aug 12th. Then on Monday afternoon I noticed i was spotting after I used the restroom. My boyfriend and I have unprotected sex. I'm not sure what it is or if it's normal. I would appreciate some great help. Thank you.
