new and just started clomid...

Hi everyone. I just stated my first round of clomid. Since my insurance does not cover any infertility, my gyn and I decided to do a very minimum amount of testing (just blood tests to check prolactin and thyroid function) and just go for the clomid for a few months. I am starting out on 50 mg. I read that some women experience some cramping while ovulating when on clomid. Any one have this experience? What other side effects can I expect? Anyone get lucky the first time around? Thanks for any insight!
