Help me please guys?

So my period was supposed to start last Friday and it hasn't yet. I had weird spotting April 7, 8 and on the 10th but it was light brownish and on one of the days it was slightly pinkish. I am only having discharge. I have been having slight cramps and diarrhea (sorry tmi) I feel like my period Isbgoing to come but it still hasn't.
