Reply to Alexander Irvine's Post: I am 20 years old. When I turned 16 my doctor started me on birth control to regulate my cycle. He said I shouldnt be concerned because every womans body is different, but as I got older and my cycle remained irregular, naturally I am becoming concerned. By at risk do you mean is it possible for me to be pregnant....yes. Usually after I eat lately I have been feeling the urge to vomit but I dont. My breast arent really unbearable tender but at times after work they do feel sore as I move around causing them to bounce or jiggle. I am always tired(:
