First time momma worries

Kelsey • 23, married to the love of my life, MMC at 9w3d in October 2019, Rainbow baby BFP 4/17/2020! Due December 29th, 2020 👶🏻 🌈

This is my first baby and I’m only 6w, I am SO worried I’ll go in for my ultrasound next week and baby won’t have a heart beat or never grew. I went in last week and we seen the sac, yolk and fetal pole but I’m just nervous. And then I tell myself even if everything is okay at this appointment then the next appointment I have after 8 weeks I’ll have a missed miscarriage 😭 maybe it’s just this app making me crazy but I don’t know what to expect!
