I was a 34b pre-op, got 445cc silicone under muscle. My boobs look really small, will that change after they drop? (Photo)

I am sorry to hear about your concerns after breast augmentation surgery. Your plastic surgeon will always be your best resource when it comes to accurate assessment and/or advice. 
It may help you to know that a significant percentage of patients at your early stage of recovery will feel that they are too big or (more commonly) too small.
Generally speaking, breast implants will "drop" into the pocket that was created during surgery. The rate of breast implant "settling" may depend on factors such as size of breast implant pocket dissected, tightness of the overlying skin/muscle layers, and size of breast implant utilized. Normally, it takes about 3-6 months (for some patients longer) to see the final result. It is very common for one side to settle faster than the other.
I routinely ask my patients to wait at least 3-6 months before evaluating the end results of the breast augmentation surgery. This waiting time allows patients to (usually) physically and psychologically adapt to the new body image. 
In other words, it is much too early to evaluate the outcome of the procedure performed; your breasts will undoubtedly change over the course of the next several weeks/months.   The vast majority of patients with your concerns at your stage in the recovery process, turn out to be much happier two to three months after the procedure was performed.  Understandably, patients often experience significant emotional "ups and downs" around the time of surgery.
For example, many of my patients report that as the swelling around the breast implants (for example, in the sternal area) decreases, they feel that their breasts appear more projecting. Also, in my opinion, the "drop and fluff” phenomenon does hold some validity; as breast implants “settle”, many patients feel that their breasts actually look larger. 
My best advice: rest,  recover, and exercise patience.  Keep in mind, that a significant percentage of patients at your stage in the recovery process feel that they are "too big" or "too small".  In the long run, once patients have adjusted physically and psychologically to their new body image, the vast majority of patients are very pleased.

Dear Honest1779,
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 weeks  post op.Your 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.

Thank you for your question. It is not uncommon to have swelling. Breasts may not heal at the same rate, causing one breast to appear different than the other. It can take up to 12 weeks for the implants to settle and you to see the final result. Give it a little more time before deciding if you are satisfied with your results. Follow up with your board certified surgeon to address your concern. Good luck!
