Anxiously wondering?

Starr
I just got back from my 12 week checkup and the baby had a heartbeat of 168 bpm. I'm wondering if it's a boy or girl? My other half has two girls from a previous marriage and I have a daughter from a previous relationship. We both really want a boy but as long as it's healthy I'm fine. I'm going back later this week for the harmony test. Any predictions?
