Please help if you can

Kelsey • I thank God daily for my blessings. Amazing husband, handsome 6 year old boy who gets a new brother due 6/11/16. 🙏😍🙏
So I'm completely aware of the nub theory. However I'm really interested in what anyone else would guess. To me, one pic seems like a boy, and other a girl. I'll post both. Please help me out with a guess! Pics taken at 12 weeks 4 days. 😊
