S.A.
I would not get too worked up over what you see on the internet. Your Doctor would know if something is really wrong. As for how big you are , it is your 3rd child. I have 4 kids, when I was pregnant with my 3rd, I was "HUGE" Doctor checked me for twins and everything, but it was just cuz i had already had 2 kids before and the fact that I was pregnant with another girl, you tend to be bigger with girls for some reason, or I did anyways. I had 3 girls and one boy. My pregnancies with the girls, I was seriously huge!!! I hope that helps ya out.
