Progesterone cream?

Jaimee
So I just bought some progesterone cream, and I'm debating whether or not I should take it back. I'm kinda hesitant, but at the same time I'm not. Anyone have any luck with it? I have pcos and am not sure if I should or not. I know my levels are out of whack, and I haven't had a period since September. I have some spotting, but I'm not sure if it's AF, or any other type of spotting. 
This is the cream I bought.
