Dizzy spells! Follow ups?

Okay ladies, question. Are any of you on clomid? I just finished my second round of clomid on Tuesday and starting Wednesday I've had crazy bad dizzy spells. I wasn't sure if you've had any side effect like this. Also, did your dr's ever do any follow ups while on it? My dr basically told me if I wasn't pregnant within 6 months then she was going to refer me to a specialist. But didn't mention anything about follow ups monthly or whatever. Any info would be great.
