I am so nervous tomorrow is my first ultrasound and I do not want to be heart broke again from my 2 previous miscarriages last year

I just wanted to vent on here I’ll be 9 weeks and 3 days tomorrow I only told one person I was pregnant because the last time I told everyone I was pregnant it crushed me because I was so happy about the pregnancy and then came time for my ultrasound and the baby stopped growing at 5 weeks and I thought I was 10 weeks. Just the thought of my baby not growing I know it’s going to hurt me again 😣 any advice ? I’m trying to stay positive here but you never know what might happen🙃
