Fertility meds

So I go in Dec. 10th to start my fertility medicine. I’m really excited but I don’t know what to expect. Anything I should know before starting? I THINK she told me I was starting Clomid? I haven’t had time to read on the side effects. Has anyone taken this a gotten pregnant.

(Not really sure why I’m having fertility issues. Blood work is normal and HSG was perfect and clear)*
