I agree with you. You can only take Clomid for up to 6 months. Why waste a cycle if you're going to ovulate and the egg can't get through a blocked tube? It's like treating a woman for infertility without a sperm analysis of her male partner/donor. A potentially huge waste of time, money and emotional and physical pain.

I'd either insist or get a 2nd opinion. I have no idea what's needed except I thought they pump the uterus with dye and see if it gets through the tubes. If that's short, then I'd wait until it's available.
