At the beginning of this month may I started feeling weird nausea, constipated, stomach cramp. So I pushed it off to my period coming in a couple weeks. Well my period ended up coming two days late. Which it is always on time. The first day was so light could call it spotting then the next two days it was heavy heavy. My periods are usually heavy to light. Well after my period ended. I'm still get nauseous and I had sex about three days after my period and later that day I noticed I was spotting which I've never had before. And it stayed for a couple hours and then it stopped. Help please
