Did anyone just “know” they were having twins before being confirmed?

Hi all,

Just being curious,

I’ve heard a lot of women say they just knew something was different with their pregnancy when they were carrying twins,

Obviously there’s a lot of women who it’s a complete surprise too.

But in early pregnancy like 6 weeks is there any “tell tell” signs that would make you believe it’s twins?

Or if you’ve had twins and a singleton pregnancy was there a difference at the beginning?
