TWIN B Guesses Please

[FiveDiamonds]

My niece is expecting twins and would like some guesses on their gender please. This is twin B. I have more pictures if needed. I can see three lines between the legs but then it looks like there's a protrusion but then at different angles I can't see the protrusion. A magnifying glass works good

I'll get Twin A's pics on next.

Thanks!

There isn't a nub showing but he head shape has me very much thinking ! They're not identical are they because I've guessed boy and girl for you

They're not in the same sac but she won't know if they're identical until they're born. I think I may have one that does have a nub. I'll post it. I was looking for the lines or dots or anything that would show the sex since I wasn't finding nubs.

Can't tell from this pic, sorry.
