Progesterone Levels - help!!

Since I found out I was pregnant (used an early response test) the doctor has had me going for HCG and progesterone tests until ultrasound is an option since I have a history of MC.

He just called with my weekly results. HCG went up and is where it should be but progesterone cut in half from last week. He said that my levels were very high last week and some doctors would say this weeks value is still good but because it was such a decrease that’s worrisome.

He’s going to put me on a progesterone supplement and scheduled my first ultrasound for next week.

Has anyone else gone through anything similar? I’m very anxious and can’t stop thinking about it.
