Ausgirl - you're absolutely right. A doppler is not going to save a pregnancy. What will be will be. But from my own experience only, I found that when you are so used to getting that wonderful BFP only to then have yet another miscarriage, the reassurance on those bad days when you have no hope that you will get through is amazing. I had one occasion where it took me about 10 very, very stressful minutes to find my little girl's heartbeat, but the rest of the time it was almost instant reassurance that today at least, my dream was still alive.

That's me though, and I do agree to a certain extent that sometimes they cause more apprehension - depends on the person. My SIL flat out refused to aknowledge her pregnancy because she was just too scared to build up her hopes.
