How soon after a BBL can I try to get pregnant?

Hello.You can get pregnant as soon as you want to.But if you want to get the full benefits of this procedure i recommend that you wait at least  4/6 months to have the propper healing and almost final resulto of your procedure.  Good Luck!!! 

The effects of liposuction on the skin are variable based upon the elasticity of the skin. The fat that is redistributed with a BBL will permanently create a favorable redistribution even with pregnancy.  The fat transferred to the butt will be affected by the total body fat percentage, and the buttock will likely get larger with pregnancy and decrease in size with weight loss.  Postpone pregnancy until you have fully recovered from your BBL and lipo which may take six months to a year.

Hello dear!
Thanks for the question and provided information as well.
I suggest you wait until having children, because, during and after pregnancy, your body will experience multiple changes, and the results of a BBL might be compromised.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)
