Mid cycle bleeding

[bushisgonein08.livejournal.com]

So I posted a couple of days ago about how I started bleeding 2 days after I ovulated. The first day was very mild light pink spotting only noticeable when I wiped. The next day it turned to bright red, but was still light enough to only need a panty liner. Now it's too heavy for a panty liner, but too light for a tampon..but still bright red. I've had light cramping in my lower stomach and back. My period is due march 11. I thought maybe ovulation bleeding but I don't think so. Then I thought implantation bleeding but it seems too early for that. Then I thought maybe I just didn't ovulate an started early..but this is nothing like my period. My last period was extremely heavy an I had a lot of clots..so a friend of mine said maybe I miscarried and my body is still..miscarrying..but if that was the case a pregnancy test should still say positive. I took a test last night and it was negative.(first response. Absolutely no second line). A friend of mine brought up that it coul be a cyst? I have never had an ovarian cyst. I have no health insurance..so I am waiting til Monday then just going to the ER..I'm just freaking out because I don't know what is wron with me..any ideas?!
