Super Nervous 😬

So last Friday I went for my first ultrasound I was 8 weeks 4 days. Everything was great the baby had a strong heartbeat of 173 ❤️ but it still worries me my next ultrasound is feb 15th I’ll be 12 weeks 4 days. I just want my rainbow baby to be okay. I had a miscarriage last year. The baby stopped growing at 7 weeks. I’m further along with this pregnancy and everything seems to be going good. What are the chances of anything happening before then? I wanna be happy and excited. I just wish I could see my baby everyday. 🤷🏻‍♀️😬
