I had breast implants put in two years ago because my breasts were malformed after having three children. Breasts enlarge significantly as a pregnancy progresses. You may want to discuss your breast implants with your attending physician. No one can predetermine what shape the breast will take during pregnancy, especially with implants. You may also want to talk to your doctor about whether the implants might interfere with breastfeeding if you choose to do that.
Most breasts return to normal after delivery.
