Very confused and frustrated

I have now been spotting for 3 days with cramps on and off. Sometimes the spotting is a little more than spotting but not as heavy as a "flow". It has been just enough to ruin my underwear but not enough for a tampon. I put a tampon in anyways this morning and just took it out and it was coated in almost black very sticky and dense discharge. I am due for AF in about 3 days and this is all that i am getting now when i use the restroom. Sorry for the wealth of information but my stomach hurts and im loosing patience. Like i either need to get my period or this shit needs to stop.
