Obviously, an in person exam, pre operative pictures, and knowing what you and your plastic surgeon discussed prior to surgery would make answering your very reasonable question much easier. That being said, yes, your nipples are too low. At 6 weeks, things will not improve very much. It appears from the pictures you sent that your breasts were constricted breasts, meaning that the inframammary fold was very tight and did not allow the implants to go below the fold. The four possibilities for improvement that come to mind are:1. Switch to smaller implants which would then allow the nipple areolar complex to be higher on the breast mound.2. Once the implants have dropped and fluffed, get a breast lift with probably some decrease in size of the implants.3. Replace your implants with a tissue expanders to stretch out the inferior aspect of your breasts which will allow for a large implant and move the nipples upward.4. Discuss with your plastic surgeon the possibility of doing a perioareolar release and 5 cuts into the tissue attached to the inferior aspect of your breast skin which causes a relaxation of the lowest portion of your breast skin, allowing the implant to drop more and your nipple to move upward.I recommend you talk with your personal plastic surgeon about how he or she views your present dissatisfaction, and what steps will be taken to rectify your downward pointing nipples.
