I really want this to happen

Elizabeth • TTC#1. 5 years and counting. Waiting for our little miracle.
This is my first month taking clomid. AF is due tomorrow. I have not really had any AF symptoms except for sore breasts and on and off sharp pains in my stomach and cramping that doesn't last very long. I did have a pinching sensation last week and then really bad on Saturday and my stomach felt different. That went away after that. Would clomid be changing my symptoms or making my cycle longer? Or did it work and I'm pregnant?
