My period restarted a week after it ended.

My period randomly came back very heavy a week after it ended and I am so bloated and have unusual feeling cramps (The front lower part of my abdomen hurts and is super tender and stinging in a few different spots) The flow is even slightly different than I get on my regular periods. I took Plan B just a couple of weeks ago. Could this have anything to do with it? I’m going to the doctor btw since this is very abnormal to me. Has anyone experienced the same before?
