In total we were trying for 10 months, I got pregnant on my 2nd round of Clomid 100g. The thing is I was ovulating already, but was diagonsed with slight PCOS as I had other indications - hair in strange places. But the FS believed that Clomid would help me achieve a "stronger ovualtion". While I am not sure what qualities a "strong" ovualtion, I guess he was right.
