fetal doppler - yay or nay?

I’m almost 13 weeks and my aunt thought it would be fun to try to find the baby’s heartbeat on the doppler and when we couldn’t find it i panicked even though we had an ultrasound yesterday of the baby moving and heard the heartbeat. I told my husband i don’t want to use that again bc then it would just make me go to the er thinking somethings wrong if i can’t find the heartbeat. What do all you beautiful women think? :)
