So I downloaded the mybabybeat app and it's been awesome. I don't get my first ultrasound until almost 13 weeks. I can pick up the quick Heartbeat on my right side a little higher. I can also pick up another fast Heartbeat on my lower left side. Would I be able to hear one beat that strong or is it two heartbeats? I'm supposedly just over 7 weeks. I'm hoping they decide to check it out at my educational appointment next week.
