I haven't really had a lot to eat today, but my stomach suddenly became very tight and felt like it was going to explode. It has gotten about 2 inches bigger than it normally is around the waist. I have also had a weird period for the last 8 to 9 months. First I didn't have one at all from September to December and then a very light one. Then in March it started and was very heavy. I had it for almost a month. Sometimes heavy sometimes just spotting. Then it went away about a week ago. I know for sure I'm not pregnant. My husband had a vasectomy five years ago and I also took a home pregnancy test. This feeling feels like a cramp like my stomach is just going to explode. I am overweight and my stomach feels firm. I don't know what this is or what I should do. Should I go to the hospital? I don't have a car and I have two kids, so I'm kind of hoping it will go away on it's own so I don't have to ride a bus down there.
