Well, we just got home from the doctor's office for our 18 week appointment...and the doc said he's 80% sure it's a boy! Apparently doctors never want to tell you they are 100% sure, but we did see boy "parts"...so I really doubt there is a mistake there! We have our "Big" official ultrasound on Monday at an imaging center where they will most likely confirm our results. We are super excited!! :)
