Heavy chest

I have felt like an elephant has been sitting on my chest the last couple days. I looked it up on google of what it could be and it says it could be anxiety which makes sense. I was diagnosed with anxiety years ago but stopped taking my medicine because we were ttc. We have so many family functions coming up that is making me stress. Should I wait it out and get through the family functions first to see if it goes away from the stress before bringing it up to my doctor? I do have an appointment in 6 days for my next ultrasound. I’m 11 weeks today.
