Possibly twins?! Help! Anyone have a situation like this?

M • wife to my ranchin’ cowboy. momma to cash and stetson and due with #3 in february ❤️

Just went for my first ultrasound today. I am 8 weeks. My OB had her tech come in because she couldn’t figure out what the other sac was. Confirmed one baby with a strong heartbeat but there is another sac (pictured to the right) that did not show a baby/heartbeat for sure. They’re not positive if it was a bleed or a sac that once had a baby or if it is indeed a twin. Anyone have a similar situation? What was the outcome?
