CD 60 & starting Progesterone. Any advice?

🦄Sarah🦋
So my doctor is starting me on Progesterone tonight due to the fact that I'm on CD 60 & I'm curious as to who all have taken this & what I can expect. He wants me to take it monthly, what day do I take it? Any advice? Thanks in advance!
I'm also taking Metformin 1000mg & going to start my first round of Clomid on CD 5-9 of this next cycle.
