brown discharge

Hanna • 10.30.13💋
So I've had brown discharge for over 2 weeks. The first few days of it I thought it was just old blood and I was starting my period. Well about 3-4 days later I got insane cramps (I NEVER cramp) and then I had like 2 huge clots come out when I peed. Like the were seriously huge. After the day I had the clots, I had light bleeding along with brown discharge still. Another week later, ever time I wipe I have brown discharge on the toilet paper. Had this happened to anyone or know why this is happening???  I thought maybe a miscarriage or something. The last time my boyfriend and I had sex was 3 1/2 - 4 weeks  before the clot.
