Ah don't worry, you never know where your placenta is and if baby is hiding somewhere in there...they have a lot of room to change position!!!
A few tips that helped me...
I found it REALLY low down, as in right on top of my bikini line to the left....I used bio oil (but baby oil would prob do it)....Move really slowly too as it takes a second or 2 for the sound to rebound back to doppler...also when i actually found the HB it was a very slight tilting movement rather than moving the device (if that makes sense) basically to just change the angle...I've read that some people dont find it one day and then do the next, I do think it takes a bit of practice! BUT also it could just be that your placenta is at the front..Maybe give it another go this morning and if still can't pick up then just hold off till scan tomo...then you'll see where baby is lying etc!!
Hope that helps a bit
