Period or Implantation?!

Faith • ✌vibes💕

So my period is 5 days late around 4 today I started spotting like little baby spots it stopped for a little bit then it started again a little heavier but no where near what a period should be I'm cramping pretty bad my hips back legs everything hurts and there's little spots of like tissue or something very small but not like my normal period I'm going to the doctors soon I just wanted to know your thoughts
