How many times you can use a fetal doppler?

I went and bought a fetal heart doppler / heart monitor eBay. I've tried and it works, but how many times can I use it in a week (not that I use on a weekly basis as an example how many times I use it), I do not use it because I do not want to hurt the baby. Has anyone else had experience with these monitors heart and how often do you use?

you can use anywhere. will not hurt the baby.

Fetal Doppler

Thus, when a get a fetal doppler to hear the heart beat?

aawwwww i want to hear every day!

You know you use it once every two or 3 weeks is good, but more than that is not good. I read an article and said that the radar waves that send sound through your belly baby like you would if a helicopter is more than your house? So babies stumbled on ultrasound and Doppler …. I do not know about you, but I'll do with him only once a month event.
