The PP is right dopplers can cause anxiety, they really only provide a snapshot, but they can be reassuring if you can find the heart beat. Even medical professionals only use them for a quick listen in. If they are worried about what they hear or what you are telling them (reduced movements, bleeding etc) then they will do a trace (CTG) of the heart beat. Which is the only way to really see everything is OK. If you are worried about bleeding or broken waters or anything else you must talk to a professional. Dopplers are not a guarantee of wellbeing!
Having said that here is a quick 101 on how to do...
Lie down when you are doing it, relax. Use plenty of gel (necessary to hear the heartbeat otherwise you will get interference or nothing at all). Try in the lower half of you abdomen below the belly button. Try putting it on your skin and angling it around. If nothing move to the middle/other side/ higher/lower.
You get 3 sounds with a doppler
- Your pulse (sounds slower and if you check your pulse at your neck or wrist either before you start or at the same time you will know if it is your pulse...it will match what you hear).
- The placenta, which will be faster but sound "swooshy"
- The baby which should be between 110-160 (if it speeds up over this momentarily, don't worry it is healthy and normal and is linked to activity amongst other things). It should sound more clipped bom bom bom bom, a bit like a horses hoof beats or a train on a track.
If the baby is moving (for those feeling it) try the side you don't feel movements on this is where the back may be and it is easier to hear where the babies back is).
If you have been told your baby is breach the heart beat will be at the level of your belly button or above (usually).
If you have been told your baby is back to back then try right on your belly button or just below.
If you are worried about movements (and over 24-26 wks)
even if you hear the heart beat, you should be getting checked out by the midwife. The only way to know if things are OK is to do a trace (ctg) of the babies, heart beat for around 20 min or more and look at the over all pattern. Before 26 weeks (ask your midwife you hospital's policy on gestation) it is not expected that you will feel movements consistently every day.
Sorry it is so long but I hope it helps.
