I'm 10 days late with my period w/c is due 28th of the month with occasional lower back pain and lower abdomen cramps, I took hpt and got faint positive pregnancy test result, on 11th day I had little pink discharge w/c turns out light brown and now dark red and brown now, but still so few that I don't have to use sanitary napkins, yesterday I've tested again with hpt and turns out faint positive again, could I be pregnant or mc? I've scared, I feel lightheaded but no more cramps just mild lower back pain and I don't know if I'm just stressed, I got married last December and we're trying to conceive. Also I was diagnosed with pcos in my left ovary. What's happening to me? Is just I'm stressed but why I got two positive hpt tests?

Thanks a lot to ease my mind.
