PLEASE HELP (PART TWO)

I posted this like a week or so ago and today I’m supposed to get my period but it has not come. The bleeding mentioned in the post stopped after a day. I haven’t had any bleeding since.... my period is supposed to come today and I have a feeling I’m not going to get it. If I don’t get it by tomorrow I will test. Was this bleeding implantation bleeding? What should I do??
