Light pink discharge? Ovulating?

Jessica • From Iowa, 25 years old and trying for our first baby.
I am not supposed to get my period for another 16 days, and today I have been having awful cramps (like a period) and tonight I have a light pink discharge. This has never happened before, is this a symptom of ovulating? Or am I just mysteriously 16 days early? Just wondering if this has happened to anyone else?
