Stopping progesterone

Did anyone have a hell time weaning off and eventually stopping progesterone? I’ve been too anxious to stop it this pregnancy after 12yrs TTC, 4 losses and no LC but my OB assured me I was safe to do so, so I started weaning (800mg pessaries daily to 400mg daily) at 14 weeks and I’ve been feeling like utter hell the last few days. My head is killing me. My emotions are a mess. I was JUST starting to feel good again after a rough first trimester. Will this ease soon? The way I’m feeling I want to go back to 800mg and stay there forever. Feeling so awful has made me extra anxious about my baby’s wellbeing too. I don’t trust my body after so much loss.
