On May 6th I began what I thought was my normal menstrual cycle but it was very light, lasted about 1 1/2 days and then was gone. Almost 2 weeks later (after having sex the night before) I woke up with bleeding. Over this past 6 days I have had constant bleeding and cramping. It's very little on a pad but quite a bit when I go to the restroom, including some clotting. Just wondering what could possibly be going on. I am 38, have always had very regular cycles and do not use birth control (I have 2 children, never used birth control and have been married for over 15 years). I wondered if I could have been having a miscarriage (even though the last time I was pregnant was 12 years ago), I've never had trouble with bleeding during pregnancy and I took a pregnancy test just to be sure and it was negative.
