Period 7 days early 🙄

Charity • Dying to be a First Time Mommy! 💕💕

My period wasn’t suppose to start until the 14th of this month! Bled for three days. Absolutely zero cramping which is not normal at all! I normally am in misery with cramps. TMI but normally the second day I fill up quite a few tampons. This time I filled up maybe one. I felt nauseous more than normal but absolutely no cramping! Can someone explain this to me?
