Oooops, so many girl-guesses. 
For some reason I thought that the three spots I saw between the legs are boy parts, cause I didn't see any proper lines either. I came here to get some sort of "back up" for that thought, so I could get past that "what if it's a girl -curiosity". Well, It didn't quite happen, and now I'm even more curious... 
I'll add some updated photos after a week, maybe some development can be seen then. Until then, I'll try to kee cool (yeah, right). As I'm new here, I don't know how "educated" anyone of you are on this. However, so many girl -guesses makes me think, could you all be wrong... 
Guesses are still very welcome, and if Charliecats has the time to say her opinion, I'd really appreciate that. 
Anyway, only time will tell for sure... I'm super excited!
