Well over a year ago I started to get my period for 3 weeks out of the month instead of the other way around! At first I though nothing of it, I though it would go away. After a few months of this happening I went to my Doctor. All he could tell me is that I needed to switch Birth Controls. Since then I have been on six different birth controls and had a pelvic Untrasound and still nothing. From switching birth controls I am emotion, I am gaining weight and I feel like I just can't do it anymore! I am 20 years old, and not overweight. Yet everything I am reading is showing things like this happen if you are overweight, going through menopause or Pregnant. I am not any of those!!! I NEED to know what is going on!!
