Although everyone is different, your results will be relatively stable with pregnancy and weight gain. Once the fat is removed from an area with liposuction, the fat will not regrow in that area with weight gain. And with pregnancy, it is usually the upper abdominal tissue that becomes stretched, not the mons pubis. For many women, fullness and extra skin in the mons pubis are related to genetics and very amenable to surgical correction with long-lasting results.
