Can pregnancy cause you to suddenly be sensitive to certain materials? I've had my ears pierced for most of my life. I've been wearing the same 3 studs for the past probably 3 years and now, my ears are super irritated. I am sensitive to fake/cheap metals, but the piercing that's the most irritated was real White gold! This is my second pregnancy and nothing like this happened with my first. Plus I have a cartilage piercing that is perfectly fine. I'm so confused?
