I don't want to sound rude but first and foremost lose weight and get your health in check. If it is a hormonal balance losing weight could definitely help. Good luck
I went thru this same problem. I had to loose a good amount of weight and my periods have been coming some what regular. I did get on some hormonal pills to help with the irregular periods and to help stimulate ovulation, bc I wasn't ovulating like I was supposed too. My dr told me about some medicine, Fertibilla - Concieve Easy and I've been on that for about 2 weeks. Working great so far. Good luck!
