Home doppler

Sabrina • married mamma of 3 beautiful babies!!!!!
Anyone have a home doppler and want to give me insite? I've had my doppler since I was 16 weeks with my son and used it through both of my sticky pregnancies. Ok so I had an odd 48 day cycle got faint positives neg blood test then bam af but af was only 2 days and very light my 2 year old found my doppler and when I was showing him how to use it I heard the oh so familiar wind in the trees sound when I pushed really low like my skin hurts that's how low I pushed. I can't get a test for another week but do you think I'm just hopeful and I'm mistaking gastric noises or is it the plasenta that only makes that noise?
