Then don't get one. They're not recommended because so many women either panic when they can't find the heartbeat or don't seek medical advice when they feel something is wrong because they can find the heartbeat.
I've got an Angelsounds doppler and found it really reassuring. You have to use lube of some description to move it around and you have to spend a little while angling it in different places and in different directions - but I certainly heard the heartbeat loud and clear at 14 weeks and used it often after that.
The nice thing about the Angelsounds one is that you can attach two sets or earphones so you can both listen together .
I used an Angelsounds one from about 16 to 23 weeks for a bit of fun and to help DH get his head around the fact that there's an actual baby in there all the time not just on the scan monitor!
If you do decide to go ahead, use LOTS of the gel and go low. If you know you are a worrier you could restrict yourself to a couple of listening sessions a week as not to become too obsessive, and only use it with someone else there (the Angelsounds one has two headphone sockets).
Agree that it has the look and feel if cheap crap!! Oh, and the translation of the instructions is interesting, but working it is a bit of a no brainer so not a problem.
i have a pocket doppler, i think i got it second hand off ebay. I am also a worrier, and after 2 previous miscarriages I wouldnt be without it. with my first DD we found the heartbeat at 12 weeks, second DD 10 weeks, and Im currently 9+2 with my third and we heard the heartbeat clear as day last night. I wouldnt be without it. Just be prepared to spend awhile searching for it as it can be tricky depending on where the baby/placenta is.
I have an Angel Sounds doppler and found it really useful early on. Just make sure you use some lube with it. It's so reassuring and actually, really lovely for DH as it makes it more real for him in those early days.
I haven't used it much in the last few weeks (31+3) because as soon as I felt the baby move I didn't feel the need. Though if ever I don't feel much for a while, I pick it up again.
