Overweight Amenorrhea

Hi there! I'm new to Glow, just wondering if there is anyone else out there who is currently experiencing amenorrhea(lack of a period) due to being overweight? I've had irregular periods my whole life and it want until recently that I found out that it may be because of my weight. My doctor is not supportive at all, so im looking for other experienced members for guidance!! Currently losing wright so we can TTC!!
