Your question is a good one.
What you have to ask your self is this, if you have the surgery now and in 5 years (after a pregnancy) you grow dissatisfied with the appearance, would you consider then having another touch up procedure?
If the answer is no, then I would wait until you are finished having babies.
If it is important for you to look your best now and the potential for needing a post pregnancy revision doesn't frighten you, I would go ahead and have the surgery sooner than later.
All the best,
Douglas Hargrave, M. D.
