Hello everyone! Maybe someone has encountered something like this?

Hello everyone! Maybe someone has encountered something like this? According to obstetric weeks, it was 9, but on ultrasound they said 6-7, they said that there is a 2 week lag from the norm. After questions, they suggested that it might be late ovulation ?‍♀️ They scheduled a repeat ultrasound in two weeks. I'm worried, I just hope everything is okay ?
