I took Plan B 5 weeks ago and I didn't have my period at all, I just bleed for 3 days it started like spotting then later on it came out to be light to heavy and light but only for 3 days which is not my normal days for my period. I began to vomit whatever I ate, I would get a brown discharge and now I'm cramping but there's no blood at all am I going to get a period for the next month or is the pill reacting to it ?
