Two heartbeats?!?!?!?!

Little Blessings Mom

Hey ladies! So Iwas using my fetal doppler and I always test the left side since thats the side my OB found my baby's heartbeat on. Well this morning I tested the left side and got the normal 155 Heartbeat, but then I decided to try the right side and I found another heartbeat at 122. I moved it back to the left and got the 155 HB then I moved it back to the right and got the 122 HB again. I did this about 2 more times. Same thing happened.

I've had 2 ultrasounds at 4 weeks and 9 weeks, and OB only saw one baby.

What could this mean? Tell me what you guys think!
