starting clomid next week

Yesterday I had an apt with my doctor. We decided to try clomid. I'm going to take 50mg for 5 days. It seems like a very strict schedule, so I'm a little nervous.

CD 1-call my doctor and let him know my periods started

CD 3-blood test

CD 5-9-Take clomid (fingers crossed I don't get horrible side effects)

CD 12- model cycle ultrasound to look at my eggs

CD 21- Blood test to see if I've ovulated.

This is my 1st round on clomid and I'm a little nervous. Any success stories out there?
