Progesterone

Je

Today at 5w5d, my progesterone was 21.

In the prior weeks it was 22 (4w5d) and 19 (3w5d).

Is it okay that it dropped a little? My nurse said it was but I don’t really trust her lol. I’ve had 3 prior miscarriages and I’m on suppositories. My first scan is Monday. I’m just so nervous. Thanks!
