I took Plan B One Step 2-3 days before my real period started. It was normal. Now about the time when I am supposed to get my period the next month, it’s heavy the first day. Then the next day it was super light. Then it was spotting the next 2 days(dark brown little spots) and then nothing. It didn’t last as long as it was supposed to. What should I do? Any advice? What is going on with me?
