I must be very lucky. I don't get any symptoms on Clomid except mild abdominal cramps. It seems different people react very differently to it.
Laura, I think they'll put you on Clomid once they've done the basic tests to see what the problem might be - blood tests, sperm analysis, HSG/lap and dye and ultrasound. In my case, I had ovarian drilling done at the same time as my lap and dye, so they gave me 6 months with that, but then they put me straight on Clomid when I hadn't got pregnant.
