Nervous about u/s tomorrow

🎀 Nat 🎀 • Baby Girl Mom/ May 2019 💖 #Babynumber 2 due March 2021 💖💙

Have my first u/s tomorrow ill be 7 weeks 1 day. Paid privately for early reassurance as having no symptoms. Scared that i will go in and there be no heartbeat. Anyone else had this happen to them and turned out everything was ok?
