Spotting??

I need opinions ladies! So on cycle day 24 at bedtime I had little bits of pink spotting, through the night it got a little darker, rusty, slightly more volume but just enough to make the toilet water change color and some in the Tp. No clots, slight cramping. The next day all I used was a one panty liner, consistency was mostly brown mixed with a bit of pink in am then by the afternoon it was all brown. Day 2 (yesterday) was all brown, more like discharge mixed with old blood, dark brown. Today I'm only having brown discharge when I use the restroom. So 1 day of  light rusty/pink spotting, and 2 days of very scant brown discharge. Would you ladies consider this a cycle???? AF would be due tomorrow if I was on time. Should I test?? If so when should be a good window to test??
