Every month for the last 6 or seven months (maybe even longer), My period has come on early about 3 or 4 days. It was coming on around the 18, then the next month the 11, then the 9, 4, 2, 30, 27, and now the 23. Can somebody please tell me what could be wrong. Could it be my hormones off balance, or what, I really want to try to concieve soon. By the way, my cycle are really, really light the first three days, on the fourth it is heavy and I cramp so bad, that sometimes I can't walk. It youst to be when my cycle come on it would start off heavy and slowly lighten up and it would stay on for about 3 or 4 days. Let me add that I am really over weight and I also lost two babies. Please help me.
