Hoping, Wishing, and Praying!

OBGYN put me on Letrozole this round and my follicle sizes were around 27mm.much better than last month. My progesterone check was around 15.6 so he thinks I ovulated. I've been having horrible mood swings,, slight cramping on/off for past week, extremely fatigued. I don't want to get my hopes up but it's so hard not to! Doctor says to test on Monday if AF hasn't come this weekend.
