Bumps to big, this bloating? Something else?? is this normal

From my last missed period I'm 11 weeks, I've had an early scan that dates me at 9-10 weeks today,that scan was taken 4 weeks ago when they said I was 5-6 weeks then,

bit I've just grown and grown and grown??

I wasn't what you would call think and toned before but I could see my feet!

And was never round like this, just a bit wobbly 🙈, mummy tummy.

This is my 4th pregnancy but 2nd baby as I had 2 ectopic pregnancys,

Scan defiantly showed only one baby,

I'm just a little worried that something could be wrong thats making me swell up like this, is that possible??

Thanks

Xx
