I had 335 cc silicone implants put in 7 weeks ago . I was a very small A cup before with very thin skin from nursing and weight loss . I have thought they are too small from the second day post-op. My PS stated that he could not fit any larger of an implant in my body . My question is that , with my frame ( 5'5 135 lbs ) is this necessarily true and if so , how long do I have to wait to go larger ?
