I haven't had a period since before Halloween and I've taken two pregnancy tests two weeks apart from each other and both are negative. I don't feel pregnant at all. I was on birth control since June 2011 and stopped it October of this year. I was told that it would take a little while for my period to come back but the doctor said it shouldn't have taken this long. So, I thought that if I was pregnant I would at least have some symptoms but I don't. So am I pregnant or is something seriousm wrong with me??
