Clomid - any tests before prescription?

Ke
Hi - just curious - did your obgyn perform any tests before prescribing Clomid?   I am 40 and my doctor told me to see her after 3 months of trying. I assume Clomid will be the next step. I know some tests have to be done on certain days of my cycle so I didn't want to miss a month because I didn't make an appointment at the right time. Thanks!
