I recently noticed that I have gotten a little 'big' in the belly, but my belly isn't soft, its kind of hard. I don't have to use the restroom, gas, or bloating, its been like this for a week and I feel normal. I've been sick, throwing up, for three weeks, especially in the mornings and sometimes the evenings. I had protected sex, and the condom LOOKED like there was nothing wrong with it, the stuff was still in it. Its been about a moth since my last period, but I can't remember when I had my last period, exactly. Could someone give me some advice?
