First cycle of Clomid

Mrs.N • 26//married—TTC#2
I went to my gynecologist Tuesday because I was on cycle day 78!😳 So ironically I started my period naturally yesterday (Wednesday) after just being prescribed provera & clomid. I called my doctor and I will start my clomid tomorrow. I am nervous, I have never taken medicine like this. Any similar experiences & how long were you ttc before BFP with clomid! 
Thanks yall & baby dust! ✨✨
