My mother had her 'period' for three months before discovering she was pregnant with me so I worry a little even when I have my period. I've always been very regular, every 28 days, until I became sexually active a year ago. I've had pms ever since and the last few months my period has been strange. The pms had gotten rather bad and I was bleeding heavier, thus I suspected that I have endometriosis or fibroids because both my mother and grandmother developed those issues around my age. Around the beginning of february I got a virus or something from a friend and was sick (coughing, sneezing, fever of 104.5), but then I began to feel better, but became nauseous. I figured it was just the flu hanging on. Now i'm not so sure. It's been a month and i'm still sick. I get nauseous and have heartburn every day no matter what I eat, even if i just drink water! I've been getting dizzy and have been so tired lately I fall asleep by 9, though sometimes I can't sleep at all. I barely eat anything, nothing sounds good, except for mayonnaise on toast with pickles, which would have made me throw up a few weeks ago. My period has been odd too. In february it was a week late and stopped after 2 days only to return a day later for one more afternoon. This month it was four days early and really light, barely there kinda light and an odd brown color. I haven't had pms, but my period isn't due for another two weeks and I feel all crampy. Are these pregnancy signs or could it be something else?
