4 week progesterone level

I’m currently sitting in the doctor office waiting to get a pee test to confirm my pregnancy with them. I asked when I got here about checking my progesterone and they said they would have to check with the nurse. My bbt dropped a little bit this morning and I’ve had 2 chemicals before so I’m just concerned. I feel like the nurse is going to say no though because I’ve asked for suppositories before because I think I have low progesterone and they said it wasn’t needed.
