How much weight should a Chubby mummy lose?

I have a pretty un-healthy BMI of 31.4 :(
I am 194 pounds or 88kg
Should I be aiming for a certain amount of weight loss?
Or just start at 6 weeks?
I have lost 3 this week assuming I am a good girl I could lose 10kg in 6 weeks or 22 pounds pretty easily I think.
My BMI would still be to high but would that be enough to sway my odds?

Could I ask what you weighed when you conceived your little guys? :)

I actually weighed less when I conceived my boys, this is the heaviest I've been.
I kept saying I was going to exercise and eat less but it never happened. lol

Heavy weight also sways pink! I have a REALLY heavy friend, and last month she confirmed she's having her third girl!

I weighed less when I conceived my 2 sons I was a UK size 12 this time iam having a girl and iam a UK size 14 I didn't want to do the diet as I figured weighing less didn't help me b4 xx

Thanks ladies.

Ds:2 75kg
