Advice on Side profile guessing @20 weeks?

Hi experts!
I have my 20 week scan on Thursday. I dont think I can find out as I am too nervous yo hear boy and not ready for that news just yet but still would not mind a gentle clew that might help me ease into it...if u know what i mean?! :-)
So..does anyone out there know if there are any specifics i should look for down at the bum area for boy or girl? I guess if i am not finding out the sonographer wont do a potty shot so I need to look myself at side view! Any tips..i know nub wont be visible. At my 11 week scan..i saw nothing!! Thank you all. Any words of wisdom are welcome

I guess just look for lumps and bumps down there although I know they say the absence of a visible penis doesn't mean it's a girl. And girl bits can also be swollen so its prob not easy to tell without a shot between the legs x

20 weeks should be easy to tell. With my 4 son's I knew the sex at 14 weeks and 5-6 days.

Here's a pic of my 4th son at 14 weeks: https://sphotos-b-lax.xx.fbcdn.net/h...27296469_n.jpg

I hope all of these help!!!

And for my daughter..her gender ultrasound is tucked in a scrap book. Her's was at 14 weeks and it was just a "blank" spot" and three "hamburger lines".

Sushikitty do you have any nub shots of your boys? I'm really struggling with my nub shot but it was quite early at 12+3 so not sure what to think!
