My boyfriend and I always have unprotected sex and he ejaculates in me 98% of the time but I have not been able to get pregnant after, almost 2 years ago I had an abortion that I think, since I was also sick when it took place, I may have gotten an infection (or that there may be possible scarring) which could have caused my not being able to get pregnant. I did not want the abortion but it was the best choice at the time. Now I would like to have a baby, but ever since I have not been able to. I always have had a normal period. I have not gotten my period yet for this month and it is almost the end of the month. I have been feeling sick (head colds, swollen throat, fever, etc.), nauseated, very irritable, tired (but have trouble sleeping), sudden food cravings, constant need to urinate, and a larger appetite than usual. Just tonight, 12/23/07, I woke up in the middle of my sleep unable to breathe due to excessive gas. I woke up around 2 this morning and have been burping ever since and it is now 3:43 a.m. It started as a burp almost every 5 seconds then slowed to about every 30 seconds and now it is about every 5 minutes or so. I have been very mean to my boyfriend about the silliest things lately and I do not understand what is happening. I also have taken home pregnancy tests but they turn out negative. Could I have an ectopic pregnancy, a miscarriage, a cyst, or could I be pregnant it is just not showing up? Can anyone help me with any information? I do not particularly want to go to a hospital but I may not have any choice. I hope there is someone who will understand my situation.
