Anyone know the sex yet?!

Heather • Greyson Benjamin born 4/6/16... Little boy stole my heart 💙
I had an us on Friday for my specialist, I asked the us tech if she could tell the sex and she said she couldn't.. I have my next ob appt on the 20th, I'll be just over 15 weeks. I'm hoping they can tell.. I've seen others who found out around then. Otherwise, it'll be around thanksgiving!
