Plan b when ovulating

Took plan b when I was already ovulating; over the weight recommendation and didn’t realize there was one. My period was due the 10th but..it’s always heavy and it was very light to the point it wasn’t really there. The bleeding lasted 7-8 days (not normal for me anyways). I had very little to mild cramping. My periods give me the worst cramps. One day I had this pulling/pinching pain at the lower part of my stomach and last for a few minutes. My symptoms include:

•headaches/migraine

•bloating (more than usual)

•increased hunger

•body temperature( warmer than usual)

•joint pain

•back pain

•nausea

•more fatigue

•weird cravings

Anyone have any idea why I’m experiencing these symptoms as to I never get unless it’s cramps..?
