Am I early or going to miscarriage?

Gi • Zeir 👶🏼💙 3.18.20 Tre 1.18.23 👶🏽💙

I'm supposed to be 10 weeks since my last period was september 9th but today was my first ultrasound and they told me they couldn't find my baby it was just a dot. They said I might be earlier than they thought but my period has been gone for almost over 2 months. Has any had this and baby turned out to be okay? Please any answers i'm freaking out right now..
