My wife is 30 weeks pregnant and we have had a fetal doppler since 13 weeks. Recently we have started to hear irregular beats although a check at hospital told us everything is normal and to stop using the doppler.

If you listen to the baby lower down under the belly button the heart beat seems almost regular. Listening just above the belly button the beat sounds regular, then changes to a slower double beat like a "chew-chew…….chew-chew". I know it is not the mothers beat but why this double beat? Is this listinging to the in / out flow of the umbilical cord to placenta? Anybody else experiences this?
Thanks for all the answers, very reassuring to hear that things do not always sound perfect. I thought that the placenta was just a continual wooshing sound rather than a beating sound though.
