Has this happened to anyone???

P

I am 9 days late (I have irregular periods) 4 days go I went to the restroom wiped and saw brown discharge I saw this for 3 days but only when I wiped.. the 4 th day I had some pink blood on my tp after wiping. Today 5th day nothing but pain in my lower stomach first it was on my right side now just in that whole area feels like some strong cramping but it comes and goes?? Should I call my dr or wait it out to see if I’m staring my period?
