Miscarriage Support

Hi everyone,

Three weeks ago I got my period late, it was a bit heavy but not abnormally so and lasted for about four days. Three days after my period I started bleeding again. This time it was very heavy, so much so I had to leave the college I am attending to clean up. I had started bleeding so hard I bled through despite having just changed. When I got home I cleaned up and changed and started working on homework. Within an hour I stood up to take a quick homework break and I felt a gush. I had bled clean through again. By this point I was really scared, but I have no insurance and couldn't just call my doctor. The bleeding subsided within the next few hours but continued on till the next day. I made and appointment to see a doctor at Kaiser despite having no insurance and was seen a couple of days later. The doctor told me the bleeding sounded like an early miscarriage, but when given a pregnancy test I was negative. The doctor checked me for fibroids as well and I did not have any. Since the doctor couldn't explain the bleeding he told me to go home, rest and the bleeding would stop on its own. After the doctors visit the bleeding lasted another week . I finally went to Planned Parent Hood because I was still bleeding and couldn't afford another $80.00 just for a doctor to tell me he didn't know what was happening. Planned Parent Hood told be to take Motrin and this would help stop the bleeding.I have an IUD, Paraguard, so the chances of getting pregnant are slim. Could this have been a miscarriage? A friend of mine who had an early miscarriage thinks so. I had thought that I might be pregnant when I had been late for my period,however this is the first thought that pops into my mind whenever I'm late. Does anybody know what could have happened? Does this sound like a miscarriage?
