fetal doppler How often do you listen or try to listen to your baby's heartbeat at home?

I had a friend give me a fetal doppler shortly after I found out I was pregnant, I've used it about 5-7 times at the end of the first trimester and beginning of the second trimester. Ever since I've been able to feel my daughter move at 22 weeks I haven't used it at all since and I'll be 36 weeks on Saturday.

I used it about once a week for less than 20 seconds each time from weeks 11-around 16.
