Progesterone Issues

So I started HRT over a year ago. Estrogen and progesterone. Well immediately I couldn’t tolerate progesterone. It made me feel anxiety and palpitations hour after taking it. Doc then put me on Slynd (synthetic progesterone) and it wasn’t perfect but definitely way better. A couple of months ago my doc says - you’re about to turn 55 let’s take you off of Slynd and try micronized progesterone again.
I’ve been on it for 45 days now. I have had debilitating headaches about 30 of those days. I mean headaches that feel like migraines and they last 3-4 days at a time. I also get stomach anxiety and strong beats ( not necessarily increased heart rate, just stronger) almost every night. Oh and now I can’t fall asleep early. I don’t get sleepy til 2 am, so some type of insomnia too. I need to stop progesterone asap. Has this happened to anyone? Please share your experience. I need help!
