I'm 19 and was on birth control for about three years to regulate my periods. I got off of birth control 8 months ago and my periods have been irregular since then. At first they were very light, but over the past couple of months they seemed to be getting heavier until last month when it never came. There no possibility I could be pregnant (no sex) and I'm not especially surprised that my period is late (about 3 weeks late). What gets me is that I seem to be experiencing intense prolonged pms symptoms that are just getting worse. About three weeks ago I experienced a few days when I was incredibly dizzy. Sometimes I still feel dizzy but it's not that bad. Now I'm just bloated and getting more bloated. I've been having bm's about once a day but my lower abdomen still sticks out and feels very solid when I press on it. I've gained about 4 pounds even though my diet hasn't changed and I work out regularly. I've been feeling tired and depressed.
