Need help due date? Screening!

hailee • Momma to 3 beautiful baby girls && baby #4 on the way🫶🏼

I had a dr appointment Tuesday and I was 15 weeks and 5 days. I had blood drawn for a bunch of different screening and I got these results back today. It says gestational age from blood drawn is 22.7 weeks but through ultrasound it’s 15? What does that mean or has anyone got results back like this? Maybe it’s normal but I’m just curious.

And my last ultrasound was on 5/26/2022 I was around 8-9 weeks. My due date is January 6th. I’m just confused
