Are my nipples healing normally?

Hi all! I’m just a bareky over 4 weeks post op and so far I think everything has been going great. I’m just apprehensive and anxious about my nipples and want to Be sure I’m safe rather than sorry . They had already peeled off all the way and I think they were more pink when that happens and have slowly turned darker and I just wanted to be sure that’s normal. Second thing is I still am waiting for 1 last suture to come off and wanted to be sure after that goes that I can shower without having to worry about damaging it LOL.
thanks for reading and your help! -sincerely over anxious worry wort 😂
