Uterus position?

Nakita • 30 years old, Married Baby 1- June 2015, Baby 2- October 2016, Baby 3- March 2018! Baby 4 October 2019

At my last appointment I was just over 14 weeks and she said my uterus was almost 2 inches above my belly button. This is my 4th and I was pretty shocked as it's not suppose to be that high up. Anyone else experiencing this? We have an ultrasound in June that she said we will see if it is possible multiples??
