I still say girl.
Somehow I cannot imagine you are really pregnant.
When I was three weeks pregnant I had to start wearing maternity clothes. By the time I was 20 weeks, my mom who had had 5 kids, kept asking if I was sure of my due date. She stated to the day she died she had never seen a pregmnant woman as big as me! I gained 45 lbs. Baby weighed 8 lbs. 9 oz. 21 1/2" long. She now is bigger than I am. She kicked more than my son, too.
At least you will have no weight problems and you will alway's have a nice petite figure.
Congrats!
