Currently 36DDD - will the size change once they drop?

Thanks for the question!
You are still early in your recovery, give it time. It may take 6 months for the implants to drop and settle, You will be able to see your true size at that time. Contact your surgeon with any questions or concerns. Best wishes!

At 2 months, you are about 50% dropped. The process slows down at 3 months (75%) and continues till about 9 to 12 months. Congrats and be patient. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author. RealSelf Distinguished Hall of Fame Inductee. Philadelphia, Pa., USA

In order to let the implants to drop, you should let them gently come down with time and gravity. I recommend not pushing them up with a bra for 3 months. However the size varies by the manufacturing companies. One may say DDD but another one may say DD or D. I'm sure you have discussed the size you wish with your plastic surgeon before selecting the implant.

Dear sunnydays345543,
I understand your concern and it is quite normal to be concerned about the outcome following a breast augmentation surgery. However, you are still in the very early stages of the healing process at 2 montha post op.You will need to be patient at this moment and follow what your surgeon has instructed you to do post operatively.At the early stage of the healing process, the tissues around the implants are still swollen. Once the swelling subsides and the implants drop to their final position, you will be able to see the final result of your breast augmentation surgery.

At two months post op much of your swelling has resolved. The size will remain about the same, but the way the breasts fit into the bra cup may change as they settle and soften. Your final results won't be seen for a few more months yet.

You still might wear the same size bra, but they may fill the bra better and sit better. Otherwise, you might go down in 1 cup.

It’s difficult to understand what your concern is from your post.
To make a quality assessment on the outcome of a plastic surgery procedure we generally need to see a complete scent of proper before and after pictures.
If you don’t have before and after pictures, then ask your surgeon to forward the pictures they took.
If you have concerns regarding the outcome of your procedure, I suggest you follow up with your plastic surgeon.
If you want a second opinion, and then I suggest scheduling those in person, second opinion, consultations with other providers in your community.
For second opinion, consultations come prepared bringing with you a complete set of proper before and after pictures and a copy of your operative report.
These are all available from your current providers office if you request them.
Best,
