UPDATE! 6 weeks pregnant with possible twins?!

Rio
Went to hospital today after being referred by 111 as I noticed my belly swelling quite badly, this is my 2nd but didn't think I would be this big? 
I'm usually a size 8/10 (uk). 
The GP has booked me in for an early scan tomorrow as she believes in further along or possibly having a multiple pregnancy. 
I'm pretty adamant that I'm only 6 weeks though due to my LMP. 
This is my bump, what do you think?
Update! Went for a scan today they said I was only 5 weeks approx! They can't yet tell as my monkey(s?!) too small! :( 
Fingers crossed for the next scan!
