My last period was in september, and i haven't had one since. Two weeks ago I took two defective pregnancy tests, took a third and it was positive. I went to a doctor and he confirmed that I was 7 weeks pregnant. I tried to go to medicaid and they needed proof of pregnancy so I took the test at planned parenthood as usual and that test came up negitive. I later I went to a lab and got the blood work done and they call me saying that the test was negitive. A week ago I had cramps and grayish-brown discharge. My doctor believes I had a miscarrage, but has not yet exammened me. :-(
