Odd spotting on period day

Anastasia

Okay so I ovulated on July 3rd and I started spotting on July 11th, light spotting only light pink when I wiped. AF was due today and I still have only light spotting with a little red and brown. Not even enough for a tampon, I'm usually very heavy my first day of AF and have bad cramping. I have none of that today. Took test, negative... I've never spotted this long and usually my periods are super heavy and bad cramps... anyone help?!
