I'm sorry to hear about the concerns you have after your procedure.
You should be aware that a significant percentage of patients at your stage of recovery will feel that they are too big or (more commonly) too small.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. 
Factors such as swelling, tissue contraction, skin redraping, implant shifting, "dropping and fluffing" etc. come into play.
From the psychological standpoint, patients undergo an “adaptation period" during which time they get used to the changes that the surgical procedure has brought about. Severe emotional swings can also occur after any type of surgical procedure.In your case, I would suggest continued patience. Continue to follow-up with your plastic surgeon.
Don't be surprised if/when you end up very pleased with the longer-term outcome of the procedure performed. Best wishes.

Thank you for your question. You are still early in the post-operative period. It typically takes 3 - 6 months for the swelling to subside and and implants to settle into proper position. Please discuss your concerns with your board certified plastic surgeon. Also, make sure you follow all of your plastic surgeons post-operative instructions regarding level of physical activity and use of a support bra. Hope this helps and good luck with your recovery.
