Any advice is welcome

Hello, 
I have been on here for a couple of months. My husband and I want a baby. I have pcos, insulin resistant, and have something wrong with my tyroid. They had recently put me on metformin but I didn't feel right and wasn't myself. Is there any other pills besides metformin could they put me on? I wanted to know if anybody that had PCOS did conceive a baby! And another question... What is a low carb diet?
