nipple piercing update!!!

So I did a post a couple weeks ago about my nipple piercings asking about after care and all that good jazz. Well it's been two weeks and two days exactly since I got them done. They're still tender but I'm also about to start my period so I'm not too worried. Uhm I've noticed they're lymphing. Today I noticed that there's this white patch or bubble right on the outside of my bar. It's not hot and it doesn't hurt until I start messing with it but even then it's not excruciating pain. Uhm idk if it's an infection or what it is. I guess it'll just be best for me to go to my piercer but did any of you guys experience something like this? And it's not big at all it's small. Smaller then the ball on my barbell.
