6 week scan!!

Hello! So, I got my 6 week ultrasound (transvaginal) . The technician scanned my uterus and went on to do the transvaginal scan. She stated she could see the gestational sac, but nothing else really. She stated that I may need to repeat in 2 weeks. Has anyone else received a scan this early and if so did you see anything? Just trying not to worry which I can do easily😕. My HCG is rising at a good rate though
