Just curious...

Has anyone had an early ultrasound when the baby's heartbeat was like around 120bpm and it turned out to be a girl? I know supposedly there is no scientific evidence that slow heart rate means boy and fast heartbeat means girl, my daughter had a 140+ bpm and she was a girl this baby has a 121 bpm so I'm hoping it's not a boy, I will be happy regardless but I really want another girl, someone give me hope here lol plus I got little to no morning sickness unlike with my daughter I was nauseated with her most the time I've read more.morning sickness usually means girl and less means boy? Someone help.me.out here lol. Knowing me I will do the sneak peek test cause I'm dying to know now what I'm having. I just don't know if I can afford it right now ugh.
