Hi, three months ago I had sex with my boyfriend. I was on the pill, although I had messed up taking it a bit and missed a day or 2, and used no other protection. Since then I stayed on the pill and had three normal regular periods. Just over 8 weeks ago I came off the pill and have not had a period since. My stomach also feels and looks swolen although I have not eaten differently or put on weight anywhere else, I have also been sick a few times. I did a home pregnancy test but it was negative. Could it be wrong after three months? Is this probably a result of coming off the pill or could I be pregnant? Please help... any suggestions?
