Pregnancy Info HOME

I have always had rather irregular periods. However, for the last year, I have had a period every month (40 day cycle.) My last period started on Nov. 19th and I have not had a period since. I am getting very worried that I might be pregnant...almost two months since my last period. We use male condoms and none have broke or slipped off. I took three pregnancy tests and they all came back negative. I have no signs of pregnancy except for feeling extremely bloated and I feel like I am looking fatter (could be my imagination.) Could I possibly be pregnant?
