I am not ttc right now but just wanted to share my excitement. I have PCOS and I conceived my son using herbs but with my daughter I had to take Metformin. i stayed on it until 20 weeks pregnant and have been off it ever since. I've been having major problems with the PCOS for the past 6 months (chin stubble - yuck!, weight gain around the middle, ovarian pain, forming more cysts, inconsistent cycles, severe blood sugar problems). The longer you have PCOS the worse it gets so even though I want more children I was kind of resigning myself to not having more. I decided to go back on metformin to try and calm down the symptoms and I've been on it for 6 days and I'm spotting! AF is on her way because I'm cramping something fierce too. I am just so excited that Metformin may actually control the PCOS for me. I want to ttc next June and it would be so wonderful if I had been regular until then and was just able to go off birth control and ttc without charting and stress. And actually know when a period is due! What an idea! Sorry to bombard your board but I just wanted to share my news!
