Using Metformin while TTC

First off...hi everyone. I'm pretty new to Glow. We have been TTC for one month now. This is the first time the hubs and I have attempted. The first two times we were not. My doctor put me on Metformin to try and stabilize my hormones while we were not TTC (having 2 peiods a month), but told me that I could continue to use it should we start trying to become pregnant. I didn't the first month because I was afraid that I would have multiples, but after asking and researching, I don't think Metformin would do that. Anyway......anyone had any luck using it? Thanks in advance!
