Anxiety meds during pregnancy??

Just entered second trimester. Used to take Ativan as needed maybe 1-2 times a week for ptsd and severe anxiety. Stopped it cold turkey when I found out I was pregnant at 3 weeks. No problem stopping it. Fast forward 10 weeks and I’m feeling so anxious and having more anxiety attacks and moments of ptsd being heightened.

I have an appointment in a few days but was wondering what anxiety meds have been cleared for occasional use etc to talk to my Ob about. My primary suggested vistiril or Valium but won’t prescribe unless my Ob does.

Also I cannot take SSRIs or NSRIs I’ve even had a full work up and psychopharmacological study done because none of them work or give me horrible side effects so they went to Ativan for rescue meds. I also can’t take buspar as it causes severe bruxism.
