Thanks for adding those pictures Raul!
If I take a look at your pictures, and all the others I've found, I would say all three girls I posted were ovulating.
It seems that no ovulation is simular to another, and some just seems to be more obvious than others.
I don't agree with this. I quess I've seen a couple of hundred pics by know of ovulating balls, but those are just pictures. In real it will always be a different story, so I posted these pics just because I wanted people to confirm my thoughts, or even to say they weren't ovulating with an explanation.
I just wasn't sure because I've never actualy witnessed it before in real.
