PLEASE HELPPPP!!!!

So I was suppose to get my period feb 19. I ended up being a month late. I started having spotting on March 7-march 10. It was brown and so light I didn't need a pad or anything. It stopped for 5 days and on March 15 I started having spotting again up until the 20. Again it was brown like dark brown. (Kind of like a poop color). So then I got my period on March 21. I had it until the 23. Usually my period lasts 7 days. Now I'm spotting brown. I don't need a pad or anything. What could be happening to me. My periods are pretty regular also. I'm just so confused. Any thoughts.
