So I got a home doppler yesterday and was SUPER excited to use it. My DH and I spent probably about 10 minutes off and on trying to find the heartbeat and then finally did. After about a minute we turned it off. Now I'm reading that you shouldn't use it more than 10 minutes a day or else it can cause damage. I'm worried I hurt my baby taking so long to figure it out...especially since it's not like I timed how long we used it.

Of course in the future I'll know where to look now and should get it quickly, but anyone want to help me feel better?
