Progesterone suppositories

I have 100 mg of progesterone suppository inserted two times a day until I either find out I’m pregnant or not. If I am pregnant on the 16th of this month I continue it but if not I stop. My question does it make you supper sleepy? I’m about to pass out standing up while at work and I’m moving around but I feel so very exhausted badly!! Has anyone experienced this!?

Also anyone got pregnant from taking letrozole, two shots of follistim and the trigger shot then doing progesterone?
