Arrhythmia with pregnancy

Has anyone else experienced this? I’ve noticed for awhile that once in a blue moon I will get an arrhythmia with my heart but since getting pregnant I notice it every day multiple times a day. I have pretty bad anxiety which I think adds to it but I’ve started getting panic attacks when it’s getting bad because I’m my head I feel like my hearts going to stop. I have an appointment with my doctor on Wednesday to discuss it but just need some comfort.
