BOY or GIRL????

We go in for an ultrasound on January 18th to find out the sex of the baby!!! I just got done making the appointment! I could have gone in sooner but wanted to make sure I was well over 18 weeks before I went in. On the phone the lady said she had an opening tomorrow and I got all nervous and excited thinking I could possibly know if its a boy or girl tomorrow! But I wanted to wait so I have the best chance of finding out the correct sex! So a few more weeks of mystery and then comes the fun part of getting things for the baby!!
