Constant vaginal bleeding with clots

First, let me give you a little run down of my life....I got my period when I was twelve.{on my birthday to be exact.} It was never normal, and I never worried about it because I know when your yong it takes sometime to regualte your period. When I was 17 years old, I realized I never got my period, maybe every 4-6 months and if I got it for two days That was a lot. Usualy, i only ever saw blood if I wipped. When I was nineteen years old, I had my first case of excessive bleeding. I bleed so bad, I was changing cloths every hour, and my pads ever 15-30 minutes. It lasted for two days though, and I was sure it was just my bodies way of "regualting" itself after so many years of not getting it. Also, I never thought to go to the docter when I was eighteenn because zI wasn't having sex and didn't think anything abou it. PLus I wasnt insured so....Anyway, it didnt regualte it at all. I started going the normal 4-6 months with iut it, though I would get it for more then two days and it was alight flow. When I was 21 I lost my virginity, and realized that I would probaly start flipping out if I didnt have my period. Again I didnt go to the docter because I didnt have insurance and the womans health centers in FL are horrid. Well I carried on like this till I was twenty two. And bam, otu of nowhere the heavy bleeding and clots. I was workign at a day care and had to clock ut and sit on the toilet half tha day. It lasted for two days as wellNot to muchh longer after that, I thought I was prgnant. I was sick and lightheaded and just didnt feel right. I took two test and they were negative. Well, my period started the 4-6 month thing after that agin andd I forgot about it. Four moe times I thought I was pregnant and I wasn't I loved the guy I was with and we had talkedabout having a baby and it was a little disscouraging to know we were kinda trying and I couldnt get pregnant. ANyway, wthis continued for a few more years. I am now 26 and since december of 2008 I have been bleeding nonstop. Some days its just light specks or maybe I willl change my oad twice. Some days its a medium flow. And some days its so heavy and I loose so much blood I feel sick. Ive counted 10 clots that I have passed in one sitting on the toilet. And they are not small either. They are gigantic, some the size of tennis balls, a few even bigger. Im sick and tired of it, and really wish they would just take all my girl stuff ou. I cant even think of having a normal relationshipp its to awful. And I am still not insured, that is the problum. If i could just get to a gyno maybe they could help. can you please tell me what to do???
