At home heart beat monitor.

Sara • I got 2 little ones, we are waiting for our rainbow due June!

I want one! But will I hear it yet??

I had an ultrasound last week and by its measurements I am 8 weeks and 4 days today and due June 20th. Can an at home heart beat monitor pick it up this early? I want to call it a doppler but not sure. Anyone else ever tried them?

TIA!!
