Ahhh helpppp cramps

I've been cramping for 5 days.. On both sides of my ovaries and now like everywhere down there.. I've been having a back ache as well n a little bit of drooling lol.. I hear it's a symptom but could also maybe just be me being unaware of my mouth being open lol. 
​opinions please:
​Would this be ovulation? Pregnancy stretching? Or af on it's way even though I never get cramps until after I get it? Idk
