Baby really big and feeling it!

Cheyenne • I am 22 and I have a 10 month old baby boy and a 2 year old little girl.
Is anyone else having this problem this early? I am 24 weeks and my baby girl Hadley is already really big (not just saying it she measures bigger everytime I go but they haven't changed my due date yet) and when I walk or lay down or roll over I can feel her pulling on my muscles and my belly stretching. It doesn't hurt but it uncomfortable. Obviously I knew this would happen at some point but I didn't know it would be this early lol so is anyone else dealing with this?
