Mine hurt so bad I took them out at 4 weeks, before I even knew I was pregnant. I am only 16 weeks and already have started leaking a little breastmilk..I am not sure if the piercings caused this or not. Even though I loved them for years, I am glad I took them out. Just a personal preference i think. Pregnant boobs and nipples change like crazy! :-)
I took mine out when I was about 12 weeks. If u plan to breast feed u will have to take them out anyway. But keep in mind when they heal it can cause scar tissue that can make breast feeding difficult or impossible. But from what ive read most other moms have not had that problem.
I think u only have to if ur gonna breast feed
