Bbaby Gender. Fetal Heart Beat, Sickness?

Hi. I am pregnant and going next week to find out what the sex of my baby is but im just very curious to see if anyone can guess what im having. My heart beat at 10 weeks was 175, then at 12 weeks it was 165 and when I went for my 16 week it was 135. So to be honest bit curious with what its going to be. Any ideas on your experience. Im not bothered as long as the baby is healthy. Also, I have had really bad sickness the whole pregnancy so far. thank you xx
