Anxiety attack?

Prior to being pregnant, I would get anxiety attacks fairly frequently. Since being pregnant, fortunately, I haven’t had as much issues with my anxiety and depression.

Today I was sitting at work & my heart was racing, similar to how it’d feel during an anxiety attack. I was light headed, hot & my arms felt jello-y/super heavy and felt nauseous.

I’ve been having what I think are Braxton Hicks randomly the past few weeks and felt period-like cramping off and on with someone lower back pain. I’m 34+1. Not sure if I should go in to be seen or if it was just an anxiety attack?

Normally I’d probably not think much of it but being pregnant I always worry about the baby.
