Placenta Noise

I am almost 8weeks. I used at home Doppler and knew there would be a high likelihood of not finding heartbeat and I didn’t, but I did find placenta swooshing. With DD it was a soft static/swoosh, but with baby#2 it sounds super loud, like a overlapping gurgle, so busy. Can anyone describe what there placenta noise sounded like with twins? Could it be twins?
