How often did you use your Doppler?

I know most doctors don’t recommend them because of unnecessary stress.

I found baby’s heartbeat at 10w5d and had my ultrasound the next day (today). I won’t be seen again for another month. I know I’ll be stressing!!

I don’t want to overdo it, how often should I do it to ease my worries a little? Once a week until my appt? I just can’t wait until I can actually feel baby for reassurance!!
