Final due date change

Alayna • Married 10/18/14. Have 3 kids (2 natural and 1 through marriage) and Pregnant with baby #3 due 7/11
So I went to my 37 week appointment today and the dr was worried that I might have too much fluids because I'm measuring big for my dates. So she ordered an ultrasound. Everything is fine, but it turns out that I'm actually 38w 6d and due on the 11th! The best part, she's measuring a little over 7 pounds! I'm so excited, not only do I get to meet her earlier, but she's weighing less than her sister (9lb 1oz)
