it didn't work for me but I also have PCOS. I was on it for 2 months with the OB (3 pills a day for 5 days) before we finally went to an RE who ran way more tests and ended up trying me on letrozole and IUI. The only thing I can say is make sure you're being monitored while on it (ultrasound and bloodwork). Are you using it for IUI or just TI?
