Progesterone normal ?

Ne

I had another blood draw I’m 4 weeks 5 days now my last one was at 4 weeks 1 day. I went from 239 to 1,800 so my hcg is really good. My progesterone is 13 though the nurse said it was fine but every where I look online it says above 20 but her nor my doctor seem to be worried... idk what to do
