I went of the pill last month because I suspected pregnancy. About 3 days later I got my period. I did not get much period pains this month and the few I got was not as bad as always and I am a few days late for my period. I am extremely tired all the time and I get heavy headaches and get nausea a lot during the day. I have to go to the bathroom even when I don't have to go because if I wait too long I get heavy pressure on my bladder. I did 5 pregnancy tests. The first 2 showed a faint positive and the last 3 were just negative. Could I be pregnant or is this just my hormones ??
