My Fiancé and I had sex on the 10th. I started my period the 8th. It usually last 6-7 days and is heavy. Wehad sex 2 days after I started and my period just stopped minus a few spottings. The first few days it was a mixture of red brown blood and medium flow. TMI maybe... We had baby 11 months ago. My periods sometimes come a few days late, but never anything this weird. Any ideas?
