Scared of losing this baby

Haley • 24. Married to the love of my life. Caleb 👼🏻 12/21/18 Emmalee 11/25/19 🎀 Eli 10/21 😍

I have my first appointment at 7 weeks 4 days. I am so terrified. My last doctor’s appointment was with my son at 15 weeks and we found out he no longer had a heartbeat. I am so scared that I will hear those words again. Any advice?
