Who cares I think they are damned awesome as I was known to turn up for weekly dr appt's early on last preg just to know the heartbeat was still there and it was all okay and I would walk away with a sigh until a few days later I started to stress out again....another hearing of the HB and I felt so much more at peace. Seriously, if it makes you feel more at peace and calm explain that to DP that you will cause him less stress in the long run if you dont have to be a nervous wreck wondering if it has a HB still etc. Happy wifee happy man!!
