Am I supposed to be this big?

Octavia

im having my first panic attack LIKE SERIOUSLY!!! i talked to my sister today, and when i showed her my belly she was like “awwwnnn sisterrr is cuteee” until i said “yeah im only 18 weeks” she said “OH NOOOOO AND YOUR THAT BIG? your not even 6-7 months yet their gonna have to induce you if she gets to big and it gets uncomfortable for you” HOW IN THE HELL .... like what cause babies to even get bigger than their average size? is it a health issue within me? or just good eating 🥺
