Unusual Bleeding

Hannah

I've had some very unusual bleeding this month. Here's all the details: had sex on the 3rd and he came in me, ovulation was the 7th-13th. The bleeding started on the 6th, and light cramps on the 7th. At first it was like spotting, light and brown. I took a pregnancy test the 15th, was negative. So today is the 21st, and I am STILL bleeding. 2 weeks later. Its mostly been light, but as of yesterday its gotten heavier, enough for a tampon, but not enough to overflow and not much clotting, and currently no cramping! Any ideas wtf is going on??
