My last period was Jan 15th. I was due for my period on the 12th, of Feb. I started spotting on Feb 9th Light pink and sunday it turned into brown. I had spotting on and off from sunday till Feb 14th. It was so light, barely went on a pad, and you can really see it only when you wipe. I bought some pregnancy early test strips off the internet that you only need 20 mls of HCG compared to the ones in the stores. So I actually took a pregnancy test on the 15th and got a faint positive. Took another one the same day after work and got a faint positive line. I took one this morning and got alittle bit darker positive line. I started bleeding about an hour after that. Deep red blood. I had 3 very tiny, thin, stringy, clots and I'm still bleeding. What's going on? Is this a miscariage? Or can I still be pregnant?
