no heartbeat?

Lindsey

I'm due Aug 1 with my second. I'm 10 weeks 2 days. I had a prenatal appt 3 days ago and the doctor couldn't find the heartbeat. he told me typically around 10-11 weeks is when they can finally hear the heartbeat. is this true? I remember with my first hearing the heartbeat but I think I was around 12+ weeks? I've had an ultrasound when I was 6-7 weeks and I saw the heartbeat then. I was just expecting to hear it. I've had no cramps, no bleeding, nothing aswell.
