Hi there, I would like to have your ideas about those two pictures. First one was taken at 12w+4, second at 21+3. On the second time, tech said it wasn't clear so he would'nt make any guesses. Hope you'll be able to guess ! Thanks in advance !

Looks like a boy to me but I could be wrong as it’s quite blurry.
