My period was 2 weeks late. I did 2 pregnancy tests and they were negative. I started the pill after a few years break on the first day of my period. I have been bleeding for 15 days now. my period has not been normal- heavy and then light up and down and clots. i have had really bad stomach pains and nausea with some sickness. i went to the doctor who did another pregnancy test which was negative. she told me to do another test next month as she thinks i may be pregnant and it is taking longer to show up. but surely if i am pregnant i would miscarry with the amount of blood i hvae lost. i dont know what to do or think? please give me some advice.
