Baby moving out of pelvic region. Possibly further along, Multiples, Normal???

Based on my last period, today I am considered 10 weeks. I haven’t had an ultrasound yet, but it is scheduled for January 12th, and I’ll be 12 weeks.

I first noticed when I was 9wks+3 days that I could feel and visibly see what I believe is my uterus which was starting to sit below my belly button. Im adding the first picture I got from 9 wks+3days and the picture from today.

If I remember correctly, baby’s don’t usually move out of the pelvic region until ~14 weeks. Is it normal for a single baby to move out of the pelvic region before 14 weeks? Or could it be possible that I’m more then just 10 weeks or possibly be carrying multiples?

Edit; I am a twin. I was part of a triplet pregnancy but my mom lost the third baby.
