Is this normal 4 days post op to have a weird shape and nipples being so close together?

Thanks for the question. Its too early to talk about results. In my practice, after performing a BA I recommend to my patients to limit the movement of the arms for two weeks. After that, you can move your arms taking care and always with common sense. In this regard, it's not advisable to carry heavy weights to prevent the implant out of position, and allow the formation of the physiological capsule around the implant, also to avoid pain and breast swelling. Respectfully 

You look great. I don't see anything abnormal in your result. Be patient, and don't micro-manage this post-operative experience. It will be months before you see the final result.Best.

Thank you for your question. It is very normal to have a different shape or look early on then what it will look like in the long run. Your surgeon will likely have you start massaging and as they settle you should be happy. Good luck and wish you the best.
