I took Plan B One Step five days ago. An hour after taking the pill, I noticed a small patch of itchy redness on my arm. The bumps were very small and localized to just one part of my arm. However, the bumps are now somewhat on my other arm. These bumps do not look very severe, although they are it itchy. The bumps are small and often clustered together. Anyone else experiencing this ? How long does it take for hormones in your body to restabilize after taking Plan B One Step?
