I suspected that I might be pregnant, I am on the pill and that is my only form of birth control. I took two HPT and they both looked negative, with further examination that there was a very thin hair-like line slightly off center makingit a plus sign. About a week later I started getting severe cramps to the point where I thought I was going to pass out because I was light headed. I didn't start bleeding until the next day and I had heavy flow and the worst cramps I've ever had for 5 days. This bleeding stopped yesterday. Today I am still feeling bloated and look swollen underneith my belly button. I do have a little bit of cramping also. I was wondering what this could mean or if I could be pregnant after all that bleeding/cramping.
