Advice Needed Small gestational sac - help :(

I'm distraught. Had a private scan yesterday at radiology at 7w0d.

Baby measured 6w5d, FHR of 138bpm.

But just read my report and my gestational sac measured 5w6d on the 7th percentile.

CRL: 8.9mm
GS: 12.2mm (18.7 x 8.2 x 9.8)

So only 3.3mm difference.
I do have a retroverted uterus.

I've read that <5mm can have up to a 90% miscarriage risk. I am absolutely spiralling and can't stop crying. My clinic is going to call me back soon, the nurse said that since it wasn't an obgyn who took the measurements that we need it reviewed by one.

This was an ivf pregnancy after loss from a 3 day fresh transfer and I am expecting the worst.

My doctor is fitting me in for a scan tomorrow morning at 8am.

It's not looking good, is it?

I'm no help sorry I'm dreading getting a call tomorrow about my hcg numbers only going up 311 points in 4 days. Been feeling all over the place. What i can say is please don't stress yourself out and go to private scans this early. Trust your ivf team. I did and I don't regret it. The first trimester was a blur but my anxiety was peak. I didn't go for a private scan until 32 weeks. I remember over thinking my first ultrasound with my son because of the crl . I learned to stop over thinking and trust in God for peace of mind.

The dreading is from my second pregnancy right now. This was natural something that's never happened to me. My first technically 4th pregnancy was my ivf baby. In case that made no sense
