I do not know what is wrong with my nipple, I think it may be inverted. To me it kinda looks like its cracked with a hole in the middle. If this is an inverted nipple, can you tell me what grade it is? I dont know if it can be coaxed out. I also dont know if this changes anything but its only one nipple, the other nipple is not inverted. (There are also little bumps is that normal?)
