Tried 2 more times. First retry I put a pillow under my butt and moved that wand everywhere but nada.
Took a short nap while Zoe was asleep and decided WTH, one more time.
Put pillows under my butt plus I had to pee. Bladder wasn't full but had the 'need to pee' feeling so figured that would work.
Tried again and there that beautiful sound was. He/she was a bit to the left and I'm positive it wasn't my own pulse I was hearing. Too fast and just sounded different. I only caught it for maybe 10 seconds but that's more than enough. YAY :D
