Is there a complication & what do I do? 4 months post-op (Photos)

It certainly doesn't hurt to wait a year as things do change over time. I would not be surprised however if a revision will be needed to get you a better look. This may involve freeing up the pocket and possibly changing your implant type and maybe size.

Hello dear,
I'm so sorry to hear your story. Seems like your implants could've been placed in a much better position. This is the primary problem. The entering point for implants should've been the nipple. I have no idea about how your breasts were before, but I think the nipples were facing down already. So my advice for you is to focus on your nipples first rather than the implants. And at the same surgery, your implants can be repositioned in a more aesthetic way. The most appropriate implant type would be the mentor because of their round shape. I think you would be happier with this kind of implant and if they are placed under the muscle, beautiful results are waiting for you.
This is not an irreversible case. You seem quite young, you have a great life ahead of you, this subject shouldn't be an obstacle to your happiness. Especially when it's something that can be fixed!
Be safe, be happy
