gender reveal idea

Amanda
So... ladies... I'm due June 9th. I will be 15 weeks before Christmas.  I'm thinking if my doctors office won't do an ultrasound before Christmas that I may go pay to have a 4d one done and find out the gender. If I'm able to find out before Christmas I plan to get some clear Christmas ornaments and put the ultrasound picture inside with glitter the color of whichever gender the baby is. Then that will be included in family and friends Christmas presents.  Will 15 weeks be too early to find out the gender?
