Hi new ladies! Just remember not to freak out in these early weeks if you don't find the heartbeat or if it takes a long time to find. The baby is so little and moves a lot in there, so at times, it's like finding a needle in a haystack. But once you get used to the Doppler and the process (and you aquire a lot of patience), it really will help ease your mind between doctor's appointments to hear that heartbeat. Once baby starts moving on a regular basis you won't need the Doppler anymore, but it's worth every penny for the weeks leading up to that time.
Best wishes!
