Clomid, Metformin annd Dexamethasone, Will they work?

Hello ladies

Im taking 50mg of clomid and 500mg of metformin as well 0.5mg of dexamethasone. My sister said my emotions will be sky high due to the clomid...but will I feel like crap or sick feeling.

Also for everyone who has been on these pills...what are the chances of me ovulating and concieving...pretty good or nah?
