Normal?

Currently 8 weeks exactly right now, but last week at my 7 week ultrasound, I noticed the ultrasound tech used the belly ultrasound not a transvaginal. I was going in thinking it was going to be a transvaginal just like my sons but I guess I was wrong. I’m kind of scared they missed more fetuses just because my ultrasound looks kind of funny lol. My first was originally twins and I know there’s a higher chance of me having them again. Regardless, I know they will catch it at my 10 week appointment if there’s anymore, I just found it weird how odd my ultrasound looked! It’s very thin where the baby is
