I had a two day period in October which came early which is not notmal. I took a test around the 20th which came back faint positive. Took several more tests once I was late all negative except one which was very positive. The day after the second positive test 3 days into my missed period I had very light spotting only when whipping. About 6pm Thursday I started bleeding heavy I thought I was having a miscarriage however the next morning I was only spotting again and i stopped bleeding last night (Friday night) and haven't stArted back. Should I consider myself pregnant and try another test or could it have been a false positive. I had full periods with both of my previous pregnancies which I carried full term. I believe I have low hcg levels.  But I had so many negative tests and I'm afraid I'm just getting my hopes up. I've been consistently nauseous for over a month and my boobs are sore I'm sensitive to smell and my emotions have been on the fritz.
