IUI+clomid, but already ovulate regularly?

Ra
I hate to get ahead of myself but with the holidays, I tested early today. 12dpiui and it's looking negative. 
That's okay. I'm going to try to not be crushed. I want to call my doctors office before they close for the holidays, to see about getting a prescription if needed for my next cycle. 
My real question, is I ovulate regularly, husbands SA was "normal" and I've naturally conceived one child already but have secondary unexplained infertility. 
My doc said we could look into taking a superovulatory drug (like clomid, etc). Have any of you ladies had a similar instance and taken clomid with success? 
He seems really optimistic it could increase my odds to conceive, but I always like first hand experiences!
