Two BABY heart beats found on Doppler?

Let me start by saying this isn’t my first rodeo, I know the difference between my heart beat, other foreign noises in the uterus and the distinction of a fast paced baby’s heart beat. I ain’t no dummy 😉 anyways, since 9 weeks, I’ve consistently found TWO separate baby heart beats on the left and right side of my stomach. I’ve never found two heart beats before with my other pregnancies so this was a surprise. At first I thought possibly an echo, but both are STRONG and LOUD so I’m not sure. I had my first scan at 10 weeks expecting to see two since I’ve just had a gut feeling since I got my positive test but the dr. Was pretty in and out (military doctor 😒). So I guess I’m asking has anyone found two heart beats and turns out the doc missed a twin?? I’ve just never found two heart beats in two completely different spots before so it’s intriguing. Thanks!
