Dropping Progesterone


I’m currently 8 weeks pregnant. I’m worried because my progesterone has been consistently at 32 since 5 weeks pregnant, yesterday it dropped to 22. They aren’t super concerned, but they upped my suppositories from 2 a day to 3. Has anyone had a similar situation?

We had an ultrasound yesterday and baby was mearusing perfect and was wiggling away with a heartbeat of 178.
