Freaking out😫

So I'm 10weeks 2days. My OB from my first child (who we LOVED) is retiring so I had to pick a new doctor and hospital so that's all been super stressful..anyways.. We had our first appointment with the new doctor today and she was trying to find the heartbeat with a doppler and couldnt find it. She said not to worry bc its early on and scheduled us for an ultrasound on Wednesday but with my daughter we had an ultrasound and found the heartbeat with a doppler way earlier then 10 weeks.. trying not to freak out but I'm a mess..any other mommas have this happen? How did it turn out?
