I went for an ultrasound today at just under 6 wks ( early I know but I'm 3 months past a 12 wk miscarriage so my dr is watching me very closely this time) and everything looked good. I measured right on track with 5w6d. The tech was able to see a heartbeat

but... It was measuring at 88 bpm which seems slow. Has any one else seen a heartbeat this early and if so, what was it?
