Hey,

I am in the same boat - last m/c was in Jan 07, and we had 2 others before that one. I also have PCOS.

My advice would be find a good ob/gyn who specialises in fertility - even with help it can be a long road.

Metformin is a drug that affects the way that insulin is used by the body in order to use glucose. Many women with PCOS have insulin resitance, so it is often used with these women to improve symptoms - even for those women who are not TTC. For women who are TTC metformin can improve ovulation.

Clomid is a drug which is specifically used to improve ovulation.

From memory at the PCOS conference last year (through the POSAA) some studies where discussed which have shown that the most effective drug combination for ovulation in PCOS women is metformin and clomid together, followed by metformin on its own followed by clomid on it's own. But each woman's case is different so best to see someone who knows what they are doing.
