Did the progesterone supplements put you right to sleep?

I'm 7 weeks, 1d pregnant.. and was doing good with the whole "your supposed to be tired" thing.. I only got tired when I did alot of walking or excercise.. but I was prescribed progesterone supplements yesterday.. and took one.. with in 2 hours i was snoring on the couch, and still feel outrageously tired. DId this happen to you?
