Fetal doppler?

Hi so I just found out I was pregnant two weeks ago and I lost my baby in December last year. So me and my so decided to get a fetal Doppler to test it out and see if we can find a heartbeat on our own and maybe ease our worry. Have any of you ladies used one before or are using one?
