Progesterone supplement

Hello ladies! 
I've been taking progesterone for two days now (three days tonight) and I've been soooo sleepy. I'll wake up to take my BBT and then think that I've only closed my eyes for a short time but when I check the time it's hours later!! I haven't had any other symptoms yet.
