Heartbeat with Doppler?

So I’ll be 12 weeks in 2 days and on Friday I have a dr appointment. Do y’all think he’ll use the Doppler to hear the heartbeat? I’m so anxious to hear it! Also should I be having an ultrasound soon? I did have one at 6 weeks because I was cramping pretty bad and they wanted to rule out an ectopic and everything was perfect. So because I already had one will they bother giving me another? I’m located in Manitoba Canada if that helps at all.
