Metformin, femara, progesterone success

Laura

Hi. Been TTC since Dec 2013. Had 2 chem pregnancies fall 2014. I was diagnosed with insulin resistance/pcos and Started metformin Jan 2015 (750 2x/day). Starting femara this cycle (2.5/day for 5 days). I'm scared if we get a bfp that I'll mc again... Any success stories for this plan? Could use some encouragement.. We just want one more.. (I have a daughter who is 6)..

PS I take progesterone during my leutal phase.
