I am due January 4,2017 but due to having 2 previous csections with my daughters I am forced to have another one so I will be delivering around Dec 27,2016. My in laws think we are having a boy but we don't think so and neither does my family. I have the exact same symptoms I had with my first two girls and the heart rates were always high never lower than 160 and I am 12weeks and 6 days with my baby heart beat being 160. Does anybody know how true the whole thing is about girls having faster heart rates than boys?
