I am 30 and was diagnosed with PCOS about 5 years ago. I have been to an reproductive endocrinologist for a year now, on Metformin, Menopur, fsh shots and Ovidrel for 3 months and had one IUI, no luck. I can’t get my period unless I take progesterone pills or stop progesterone cream. We can’t afford anymore right now. What are my chances of getting pregnant if I just stay on Metformin without any other drugs?
