Anyone guess gender?? Please!

[piggywiggy]

Can anyone help me guess gender from any of these pics please?
The pics are from 12 wks, 13 wks and 20 wks. I'm clueless about all this, can anything be seen at all to determine gender, any response will be greatly appreciated.

There is no nub on the first 2 pic , sorry. At 20 weeks you need a potty shot. You have any?

[piggywiggy]

No, I guess I'll just have to wait it out then. Had a scan at 26 wks, the sonographer measured the baby's femur and I thought I saw a bubble type thing at the top of the legs, no pointy, penis though. Could that be the scrotum, sorry bout all the questions but my husband was with me and he didnt want to know gender so she tried to hide it from us.
