Progesterone Levels

JEM

I had a second trimester missed miscarriage at 16 weeks and L&D; last year. Now I'm seven weeks with pregnancy number two. I'm trying to stay calm (and have been for the most part), but yesterday got test results indicating that my progesterone dropped from 22.3 at 12 DPO to 13.4 at 6w5d. This can't be good, right? I'm waiting for the midwife to call back, but they were still waiting on the results from the lab when I called yesterday. Any words of wisdom or advice to keep me calm? Thanks!
