Confused???

My period was supposed to start yesterday on the 30th but it still hasn’t come on. I had very light pink and brown spotting on the 25-27 ( 5 days before my period) which never happens. It was only when I wiped a few times. I took a dollar tree test on the 28th and it was negative but my period still isn’t on. Should I retest tomorrow or just count myself out.
