Itsnowmyturn, I was saying that because a Doppler can't impact the outcome of a pregnancy. It doesn't have any impact on whether a pregnancy continues or not. The use of one cannot determine whether there's a healthy viable pregnancy there or not, or whether it's going to result in mc. That's what I was saying.
I understand what you're trying to say about the potential for false hope, but for many, many women who are suffering from anxiety as a result of mc before, they can be a source of reassurance. It won't be able to tell that person whether or not hearing a hb will mean the pregnancy will continue, but what it can do, if the hb is heard, is reduce anxiety and stress for that time, which can be very helpful.
The vast majority of the time once a hb has been found on a scan the pregnancy will continue, but no one, not even doctors, midwives or hospital scans can predict with 100% accuracy how the outcome will be.
My own personal experience using a Doppler after having previously had a miscarriage was helpful. I knew it couldn't possibly tell me if the baby would be fine, but for that moment, for that day and the subsequent days I heard the hb, it made me less anxious and more reassured. I think if someone using one can keep in mind that there are no guarantees then it won't harm to use one. But everyone has to keep that in mind anyway, at any given point during a pregnancy. Nothing is set in stone, but the further you go into a pregnancy with a healthy baby, the more likely it is to have a good outcome. That's what I was trying to say
