Boob jobs after weight loss?

i am booked to have a Breast Augmentation in August, providing i have lost all my weight i want to loose if not i will push it back till im happy with my size and weight.

I am planning on getting a lift if I don't lose any in size. And only after I am done having children. I want one more child and I know from my first pregnancy that my boobs grow fast and never go back down, so I wont do any surgery until after I am finished having children, afraid that I will get mine done and then they will grow even more. Went from a B to a D in pregnancy. Even with a breast lift, people assume that means no implants, which is not the case. With a breast lift (they use very small implants to hold the breast up in place) that I will get somewhat bigger, plus when you are lifted you look bigger anyways. Just think the difference in size with a good bra vs with no bra. Basically, that's how they would look after a lift.
