Variety of ultrasounds - Boy or Girl?

I have three ultrasounds below. I've been reviewing using Ramzi and skull theory and can't come to a consistent conclusion. Can you help?

This first is at 6 weeks and it was done transvaginally. I thought it was a nice, clear, faraway shot of my uterus (with the bulb shape), but it's unclear where the placenta is.

This one is at 10 weeks and was done transabdominally. Based on skull theory, I would think this is a boy.

This one is at 13 weeks and was also done transabominally. Based on skull theory, I would think this is a girl?Attachment 15968

Any guesses would be appreciated!

I'd say girl based on 13 week skull shape.

Thanks for the guess! To possibly explore nub, I'm also posting these two 13 week sonograms taken transabdominally. I'm not good at nub theory - can you even see the nub in these photos?

The nub looks girly to me

Thanks for the guesses! I just scheduled my appointment for next Friday. I will post on here what we end up finding out.

I'd love a few more guesses before we head in.

Any more guesses before we (hopefully) confirm in TWO DAYS!?

The bottom of the baby at 13 w is a little curved, I would vote for girl!

The combination of the 6w sono and the 13 week nub leave me thinking its a girl for for you. The first 13 week picture shows a rather flat, forked nub, which is very girly.

I'd guess girl too :)

Thanks for all of your guesses. You were RIGHT! IT'S A GIRL!!!!!! Thank you for all of your help!
