21 week Baby Face Down! That ok??

Kayla • Finally conceived after a year of trying! Born with Uterus Didelphys! 2 cervixes, uteruses, and two vagina holes!
At 21 weeks today. My baby was face down this time, and his butt was up with his feet underneath. Guess they considered him breech? Anyone else have there baby face down?? What week we're you? And is it a bad thing at all?? Hope the lil guy moves back face up!!
