Curious First Time Momma

Okay, I would love some opinions. I went a few weeks ago for my second baby appointment and at 14 weeks found out I was having a baby boy, well anyways, I'd love some of your thoughts bc this is my first pregnancy and I have a ton of people telling me I look farther than what I currently am. They based it off of my last period which was on June 22, but even that period came 9 days late only lasting 3-4 days so I'd love all thoughts.
