Starting Clomid soon. Nervous! Advice appreciated!

Darcy • 31 y/o happily married. Can't have a rainbow w/o a lil rain. 💦🌈 😇mom to 2 Angels &1 rainbow due 3/24/16. IUI/ Clomid
I have been through hell and back and today my RE told me that I'm not ovulating well (lots of false positive OPKs) and no follicles and now she wants to start me on Clomid for my next cycle. I'm scared since I hear side effects are bad. I will do anything for a baby though. Advice appreciated!
