Check this Chinese Gender Predictor out. What does it say? Do you think it's right?
I updated this calendar because the other one I put was calculating the wrong age and month. You have to know your conception date, (around 2 weeks after your period). I think this is fun.
For me it says boy. I think this is right. I also read an article that says what side of the uterus the baby/placenta attaches on is predictive of gender. Right side >97% boy, left side >97% girl. The u/s technician said baby attached on my right side. We'll see.
