Me and my husband has unprotected sex 3 days before my period started (18th of Sept), I ended up getting my period on the 21st a few days later. It only lasted about 1.5-2 days of consistent bleeding, stopped for an entire day and then I was lightly spotting another day. The last few days I’ve been extremely fatigued, crampy, and super super emotional. I can’t figure out what’s wrong with me. I took a test around lunch time and it was negative. What is going on???
