My period was a week late; one night I woke up because of leg cramps; my breast have gotten bigger; my belly and sides have been itching; I am nauseous often; i've been doing a lot of burping and I have had lumps in my throat; I have been having headaches and I often sweat at night while sleeping. I have taken two home pregnancy test. They were real cheap and came out negative (don't know if the price mattered). My stomach as gotten a whole lot bigger but its a little flabby. It's hard for me to tuck it in so...I must mention that I am a fulltime college student and I work a full time job. Therefore, I don't get the right amount of sleep and I am usually stressed. I dont know if that would have anything to do with the problems I am having or not. Could someone pleeeaaassse help me???????????????? :( I know I should be going to a doctor, but my schedule is horrible. Do you think I am pregnant??
