Low Progesterone

So I have cancer treatment when I was younger, I see a OBGYN regularly to check on my numbers to make sure I don’t have early menopause. I would rather try to conceive if it’s now or never. I haven’t had a period since Feb 3, my OBGYN did a blood test to check progesterone. The level was extremely low at <0.1. I’m still waiting to hear what she has to say. Does anyone have any advice or had this happen to them?
