“it may be a twin we’ll have to wait and see”

Madison • Momma to be💜 12.08.19

As you can see I circled two little dots. The one blob my doctor classified is 100% a baby. The other one he said could have been a twin that was being absorbed or could be a fraternal twin. I don’t have another appointment for two more weeks and I won’t be getting another ultrasound then. This was at 6W1D. Should I be planning for twins? Has anyone else had something happen like this to them? Is this just an abnormality? Should I be worried about that?
