My period ended about five days ago, and I had intercourse the day after I started bleeding during intercourse and for about a day after. I thought maybe I should have waited a little longer but I usually don't ever have this problem when I have intercourse right After so I thought it was a little strange then I had intercourse a couple days later and I started bleeding again during and it was heavier and I bleed the next day for a little while but it wasn't heavy. I'm very concerned cause I have never had this problem before. My age is 36 if that helps any.
