Last night my fiance and I had sex. I immediately went to the bathroom to clean myself up and I was lightly bleeding. However, it was redish-brown and I was cramping. I panicked. For the past couple of weeks I haven't felt myself. I have had almost every pregnancy symptom you could think of, but I took five HPT in which 3 were invalid, one was barely visible (both lines), and one negative. A few days ago I thought I started my period, but it was only brown spotting. I didn't get my period last month, but in March and April I had only spotting that lasted 4 days. I'm really confused. I'm still spotting brown but only when I wipe. Could I be pregnant? I should also mention that I have PCOS, but I know a few people who also have it and are pregnant or have had a child recently. I don't know what's going on.
