First round of clomid

Kayla
Hi ladies!
I start my first round of clomid tomorrow day 3-7! Im so nervous/excited about it. I was diagnosed with PCOS a couple months ago and my fertility doctor had my do a HSG test right away just to make sure and my tubes are open! My husband also had a semanysis and everything looked normal for him also! We have been TTC for over a year lets hope our first round of clomid works! 
The doctor started me out with 100 mg. what kind of side effects did people have and how should I expect to feel? Any advice? 
I also have a progesterone level test one week after ovulation! Wish me luck and baby dust!!!
