Are we having a boy or a girl?

I looked up some of the wives tales that "tell" you if you are having a boy or a girl. Am I carrying high or low? I am not sure, I guess low. The website I was on says that means boy but I have heard that one both ways, so... By the Chinese gender prediction chart I am having a boy and it was correct on the girls. The chart I used is here www.parenting.com/chinese-gender-pedictor/start
OK, they say if baby's heart rate is above 140 it is a girl and if it is slower than 140 it is a boy. Well we are on the border on this one. It has been slower but last time it was in the 140's so I guess it could go either way! Apparently the Mayans had an even odd test. If conception and mom's age are both in an even or odd year then it is a girl, if one is even and the other odd then it is a boy. Well I was 32 and it was 2010 so that means girl. Another one said if I was sick it was a girl and if not then boy. I was sicker this time, although still not as sick as a lot of people get. So that would mean girl, but that would also mean Sam and Em should have been boys. There is also one that calls for draino but I am not running out to buy draino for a gender test so we will skip that one. I guess you pee in a cup and add some draino to it and see what color it turns. I think it said green was girl and blue was boy. Then there is the wedding ring test where you tie it to a string and swing it over you belly. If it swings in circles it is a boy and if it swings back and forth it is a girl. I can't do that one either because my wedding ring is at the jewelry store being repaired. I took an online test here http://pregnancy.about.com/od/boyorgirl/a/quiz/boygirl.htm
I scored a 50% which they said means boy. There is also one about what foods you are craving, sweet or salty. What if you crave them all? So everyone keeps asking my if I have a feeling about it one way or the other. I do but I have terrible intuition. I was positive Samantha was a boy. She is definitely not! I have been a lot more uncomfortable this time in a lot of ways. My hips spread very early on, I was sicker and I have had a lot of headaches. So the pregnancy has been a lot different from both girls. But, I am also in my 30's this time and it is my 3rd go round with this whole pregnancy thing. It could just be that. My boobs got a lot bigger this time, which didn't happen with the girls and my back didn't start hurting until later in the pregnancy. I guess what I am trying to say is I have no idea and we will have to wait and see who arrives in September.
