Has this ever happened to anyone else and it still turns out okay?

Went for my first ultra sound sound today with our rainbow baby. I was really scared since we miscarried in the summer and it was in the ultrasound that we were told we had for sure miscarried.

I got to see the baby this time ❤️ and I could see the heart beat. But they told me it wasn’t measuring the right size and the heart beat wasn’t as strong as it should be.

I know for sure when we got we pregnant. My husband works away and I visited him on specific dates and then didn’t see him again until I found out I was pregnant so we do know how far along we should be.

I think the baby should have measured at 10 mm and we measured at 6 mm.

Would love to hear any stories of same situations. Even if they are bad. I am trying to be very realistic.

We go back for an ultrasound in 2 weeks.
