An Heirloom Tomato?

So according to BabyCenter.com the baby inside of me at 19 weeks is the size of an Heirloom Tomato. I think it's very interesting that they compare it to the size of certain fruits and veggies. We find out what we're having this Thursday morning. I have a gut feeling that it's a girl. This pregnancy is totally different.
I was sicker this time around. I don't have the acid reflux that I had so badly with Landon. I've started getting varicose veins in my upper thigh (GROSS!). And I'm carrying much smaller than I was with Landon at this stage too. I've gained 13-15 pounds so far and I'm at 19 weeks...Last time I had already gained 27 pounds at this week with Landon. If I try to flex my abdominal muscles it looks like I've just eaten a little too much. It's very weird not looking very pregnant and being just about half way done with the pregnancy. But who knows, one of my friends had two totally different pregnancy experiences and she had girls both times. Anyone have any guesses as to what they think I'm having?
