16 week appointment

I had my monthly prenatal Dr (midwife) appointment today. Everything is looking good. Heart rate is mid 130s, lower than Aly's was at this stage in the game, could it mean it's a boy? My mom did an ultrasound and could tell what it was. She wrote it down for Jeff because he is still thinking about finding out. He hasn't looked at the paper yet. I still do not want to find out but am curious as to whether he will look or not. My next appointment is May 6 and I will be nearly 20 weeks! 1/2 way there!
