Colby • Mommy to 1 boy 💙 1 little girl 💜 and two angels 💛
So I have been ttc for 2 yrs now. I have a son but it wasn't happening for me. Well I went and seen my ob and he ran test after tests and found the only reason I'm not conceiving is because I'm not even ovulating. My weight has caused me to produce more testosterone then estrogen and it's stopping me from ovulation. So now I'm one the weight loss fads and nothing is helping. Did you ladies do anything to help you lose weight to concieve? I'm 5'3" and 317lb and af is just now try to show her face after 77 day cycle.
