Tegan hun, big bellies don't necessarily mean big babies.
Just remember you've got the placenta in there as well which takes up some space.

Also, don't forget you did it wih Lily - yes she was an induction, but that wasn't because she was big.
YOU CAN DO THIS, you've done it before and I know you can do it again. Positive thinking is what you need

GO TEGAN GO!!!
