Measuring earlier than I am? Help!

Chloe • Engaged to my best friend 💏 & We are due September 22nd with our first child. 🤗 😍 We are having a babygirl, and cannot wait to meet our healthy princess. Life is great ✌❤

Okay so I haven't spoken much to my doctor about it yet, but since about 25 weeks the baby has been measuring about 2 weeks ahead. And at my apt. Tuesday at 28 weeks and 3 days The doctor measured my belly and I was measuring at 30 weeks. So has anyone expirienced this and their baby came early? Could my due date be off? Or am I just gonna have a huge baby lol

(Baby was 2.5 lbs at about 24-25 weeks)
