Question... New to this

My period completely switched on me out of nowhere in November. I had a normal 3 day period November 2nd-5th.. And then out of nowhere November 21st I started spotting.. Brown and pink mucus at first and then the next day it picked up a little bit... I assumed my period just switched...  AF was supposed to show dec 2nd but didn't.. So negative tests. I am assuming I ovulated around the 7th of December due to the amount of cm and cramping.. Two days ago I was cramping lightly but my period isn't supposed to be here till the 21st.. If it is now a new date.. My breast have this tingling and aching feeling.. They hurt so bad that it hurts when my arm hits them... Should I test? Or wait?
