I had read alot of girls posts on her about met and most say (i think) to stay on for first 3 months (12 weeks) ... get past that big danger period and then you should go off it.

I was originally put on met as a preventative for diabetes and also clomid to make me ovulate. I lasted about a month on met and got sick of popping pills all the time so just stopped.

Got pregnant 2nd month of clomid ...

Hope it goes better for you this round.
