Have your nipples (not aureolas) gotten any extra bumps?

Teresa • Hi, I'm 25. I'm so glad I found this app, I really appreciate the mommy users here. :)
I've always had bumps on my aureolas but since a few weeks ago I noticed some extra skin in the middle on my nipple, around the area where the milk is supposed to come out... They don't look like an infection but I'm wondering if anyone else has them and if someone knows if this is normal? Sorry, I hope this isn't too awkward :/
