generic vs. real?

Hello! Does anybody here that actually reads my blog think there is a difference between generic meds and the real thing? I have never had any question but now that I need to get my fertility meds prescription filled- I wonder? The real thing copay with my insurance is $130 and the generic is $20. So, I obviously wanted the generic but am wondering if it will work the same.

I know, I am paranoid but this is kind of a big deal.
