Should I wait to get a fat transfer after I get pregnant?

Yes.  Your body will change during and after pregnancy.  Some women gain excess “baby” weight.  If you get a fat transfer prior, you may not like the outcome with the additional weight if there is any. If you're not planning on a pregnancy, you can always get the transfer and do it again after.

I am not sure that anyone can give you a definitive answer for this.   Fat transfer to the breasts can be an effective form of breast augmentation for up to one cup size increase.Kenneth Hughes, MDLos Angeles, CA

Thanks for this question.  Yes, I would wait if possible, because of all the changes your body and especially your breasts undergo with pregnancy.  This is a decision that you must make based on your life situation.  Consult with a board certified plastic surgeon and they can give you their evaluation based on your anatomy.  Best of luck.
