Oh, okay. I understand. Well, I don't know if you would still hear it if not pregnant to be honest. I always heard it when pregnant and reading I've done said that it IS associated with pregnancy.
The 'mom's own blood flow' is probably right and the swooshing and wooshing is is blood flowing through those uttering arteries.
So, you have your own doppler and are trying to find a heart beat on your own? Have you been to the doctor yet? When was your last period?
Hi -- we're glad you found us. Here's the technical answer to your question-- the uterine blood vessels during pregnancy grow and give a signal producing a whooshing sound. It's normal and will be a sound you miss after you have your baby.
When is your baby due?
I don't know what it is, but I do know that it is perfectly normal. Everyone hears the same "windy" sound.
