Piercings

Any mommies on here have any piercings? My nipples are pierced and I'm contemplating on taking them out. I don't really want to; I'm 6 weeks pregnant and I feel like I can wait, but every day I look at them and it looks like my nipple is growing. I'm scared they might grow over them. I need some advice on when would be a good time to take them out or how long I can keep them in for because I really don't want to part ways with them lol
