Last day of the Clomid

Today is the last day of the Clomid! I will go in on Tuesday and have the ultrasound to see if my follicles grew. I am really nervous because I don't think the Clomid worked this time. I am still taking the progesterone and it has not been as bad/messy as I thought it would be. My stomach is killing me today and for some reason I have a very weird feeling today. I cant really explain it I just feel off. I don't know how to feel about everything this month. It has for sure been a rough month so far, I am just ready for it to be over!
