Anyone else have or had heart palpitations and hyperthyroidism (low thyroid stimulating hormone/high T3/T4)?

I was diagnosed a few days ago and I'm an anxious wreck. Haven't been able to contact my OB since before Wednesday because of the holidays. 😭

I'm currently 10 weeks 1 day. I had a miscarriage a few months ago at 9 weeks 2 days.

I have Hashimoto's disease and I've been on synthroid to manage it.

Trying so hard to find any similar experiences.

Thank you in advance!
