Is it possible to go from a B cup size to a C or D cup size with 240cc? (Photo)

Congratulations on having undergone the breast augmentation procedure. Although online consultants will not be able to provide you with meaningful reassurance, it may be helpful for you to know 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. 
From the physiological standpoint, it takes many months ( and even up to one year) to see the final results of surgery. factors such as swelling, tissue contraction, skin redraping, implant shifting etc. come into play. You may be pleasantly surprised wants to be "drop and fluff" phenomenon has occurred. You may also be happier once the swelling AROUND the breast implants dissipates and the implants' shape and projection become more visible. 
From the psychological standpoint, patients undergo an “adaptation period" during which time they get used to the changes that the surgical procedure I would send has brought about. Severe emotional swings can also occur after any type of surgical procedure.
In your case, I would suggest continued patience and continued close follow-up with your plastic surgeon.
Best wishes. 

Thank you for your question and photograph.
At present implant is at higher postion... will descend in month  time  and also reduces in size as  post operative oedema reduces. Most probably you will get full C or small D.
 Wait and watch
 Best of luck
