Clomid Newbie

First pregnancy ended in miscarriage, had two d&c's, then got pregnant again and miscarried. Then my period never came(last was in October!! Before i got pregnant the first time.) Took provera and started my first period since October... Never ovulated. So doc gave me Aygestin and Clomid. I'm a little nervous. I start Aygestin tomorrow. I had horrible chest pain and extreme anxiety on Provera. Any tips for this newbie??? Help! I know what ovulation mucus looks like but I seem to be a lot drier than normal. :/
