Girl Parts?

We went for our ultrasound today. Left without really knowing the sex of the baby. The umbilical cord was right in between the legs, and even with me getting up, walking around, going to the bathroom, turning on my side... Baby #4 would not cooperate. The technician stated that the baby was really being difficult. To which I replied 'runs in the family!' LOL!

So here is our baby! Here is the profile pic:

I'm going to attempt to explain this to you all who don't know what you are looking at - lol. The baby is laying on her left side, facing the 'camera.' On the left you can see her legs crossed at the ankles (and her little toes are those tiny dots). If you look REALLY closely, you can see a dark stripe between the legs and into her belly - that would be the umbilical cord (its more prominent in the actual pic):

And this is what the ultrasound tech is basing her semi-prediction of 'It may be a girl - but I can't say for sure' on:

Its hard to explain... but in that circle she thinks are 'swollen lips.' However, like I said earlier, the umbilical cord is wrapped between the baby's legs. Ultrasound is kinda like an x-ray though, so when she got it to go 'through' the umbilical cord, she could have very well made it go through any parts. In another version of this pic she said she thought she saw 'boy parts' but wasn't sure if it was the umbilical cord or not.

Her final prediction was she couldn't really say for sure, 'but you might want to plan for a girl since I can't find any parts.'

So we are planning on another baby girl and told the girls they are getting another little sister! Now we just have to come up with a name - that's the hardest part for us!
