Do breast implants stay bigger after pregnancy?

I got a breast augmentation when two years ago. Before getting pregnant, I was a full C cup. Now, 5 1/2 months pregnant, I am a medium-ish D cup. I feel kind of dumb asking, but after I give birth and finish breastfeeding… will my breasts stay bigger or go back to being a full c?

They will go back to their normal size.

Breast Implants-can I breastfeed?
