Hearing a third heartbeat? 😳

Hearing baby A's HB on BOTH sides of my belly always freaks me out. Like, I know it's just an echo and there are only two babies here, but it makes me secretly panic haha. Especially when there is a lot of movements the doppler on all three spots I get HBs on! Lol. The nurse measured all three also week before last (I got hurt at work and had to see a nurse midwife last-minute). I froze and she said oh it's most likely an echo since the heartrate is nearly exact to Baby A's. I breathed a sigh of relief!
