Progesterone decrease with good HCG doubling?

Michelle

I’m 6w1d and will be having my first ultrasound on Tuesday. My numbers have been the following:

12/19 HCG: 92, Pro: 17.8

12/23 HCG: 484, Pro: 14.7

12/26 HCG: 2954, Pro: 12.7

1/2 HCG: 17594, Pro: 11.9

My doctor does not seem concerned about my progesterone because they’re still in the normal range and says my HCG is doubling beautifully. I’m trying not to freak out over here because I had a D&C at the end of February. My HCG back then was not increasing the way it is now. I mentioned to my doctor that I still had leftover unexpired progesterone in my fridge and they said it wouldn’t hurt anything if I took it, but didn’t say I had to or anything and didn’t mention about prescribing anything new. Is it possible for everything to be ok despite the dropping progesterone? Is it possible that my progesterone is decreasing because I’ve had a bad cold for like a week now?
