I've always had irregular periods around every 48 days. 5 years ago I went on the pill and 3 years ago I went off the pill, had no period for 2 years, and just got my period back last July thanks to natural progesterone cream. Since then I have been regular, every month on the 13th. Well my lmp was oct 13 2011 and I have not had one since, it is now dec 21 2011. My fiancŽ and I did have intercourse on oct 30 2011 when I was supposed to be fertile, and he used the withdrawal method. I have been having symptoms such as mood swings, cramping but period never shows, hard stomach that is impossible to suck in, lol, about a month ago I was extremely tired, would come home from work and sleep from 6pm- the next morning, foods I normally love make me gag and foods I've never liked before I now do. I have taken numerous hpt that were negative, I haven't tested since about 7 weeks since lmp, it is now 10 weeks since lmp, what are my chances of being pregnant and it being negative?

Those symptoms sounds like morning sickness symptoms which means you might be pregnant. Go to you doctor and ask for an ultra sound
