Cramps Coming Too Early???

Sarah

My period was a week away when I first started experiencing moderate-level cramping. I am 4-5 days away from my expected period start date, and have needed to take a couple doses of Naproxin because of these painful cramps. This is unusual for me. Usually, I have cramping the day before, but not this far in advance. Should I be worried? Has this ever happened to you?
