uterus high

Hayley • 32 years old. MMC 8/5/16 at 13 weeks. My rainbow baby, Milo Wild, was born 8/30/17! 🌈 Chemical 11/2020. Baby girl Due 9/9/2021! 🌈
At my first appointment with the nurse last week she did a pelvic exam and felt around for my uterus. She was expecting my uterus to be behind my public bone, but was very surprised that it was already above it inbetween my belly button and pubic bone. At the time baby was only measuring 7w2d. This is my second pregnancy, though my first ended in mc. Does that have something to do with why it's high already? Or is everyone just different?
