Ok, I purchased a sonaline b fetal doppler to find the heartbeat. I have some fluff on my abdomen and its hard to register anything. When I finally got something, it sounded like swooshing sounds. I moved it to the left of my pelvis and it sounded like "wowwow", with a number of 165 decreasing and increasing......was that the baby o the main artery running down my legs sounding like that???
