Metformin and getting pregnant?


So my doctor just started me on metformin and I was wondering if anyone else has taken this with any luck of getting pregnant. My husband is getting his sperm count checked this coming week and I'm having an outpatient procedure done to see if both of my tubes are open. If everything comes back normal my doctor is going to start me clomid. We have been trying for a while, took a little break from it and now at it again. Just wanting to see if the metformin only helped anyone :)
