I have been prescribed clomid (clomiphene) am i able to also take fertilaid or a progesterone cream wcould that decrease my chances of getting pregnant?

I wouldn't: I mean no offense but - FertilAid is a waste of money. I know the website says it works, but read the fine print, even they say there's no proof. Progesterone creams are also fishy and probably not useful for 99% of cases. I recommend strongly that you work with a doctor you trust and NOT try to "do it yourself" with unproven products. Sincerely hope this helps you!
