Is this twins??

K

Hi all, I had my 12 week scan a few weeks ago and I keep looking at the scan and keep thinking it’s twins as I can see what looks like another set of feet behind the baby. When having my scan the woman rushed it and she took measurements for like 2 mins and then it was done. It was really quick.

What do you all think? Is it twins or am I paranoid🥺 please answer on what I should do. Thank you
