Dreading ultrasound ..

Ever since I lost a baby last year, I have been having really bad pregnancy anxiety and everything I feel I overthink went to my first OB visit and he couldn’t find the heartbeat at first then I heard it, and I broke down crying after I left my OB. My 14 week ultrasound is coming up and I’m trying to stay positive and not be anxious, but last year I didn’t make it to my US because I miscarried I just don’t know how to feel 🥹 I am excited, but also weary and sad because last time it didn’t go so well ..any advice on how to deal with this?
