Fetal heart tones in both sides of uterus?

Brittani

I have been able to hear the heartbeat since about 8 weeks with my home Doppler. I still haven’t had a scan and I’m about 11 weeks. I can hear a distinct fetal heart beat (160ish) on the right side of my uterus, and another around 140 on the left side. Does anyone have experience with this? Possibly twins? I have no idea. I definitely know the difference between fetal heart tones and maternal.
