Implantation bleeding

Jenna
Hello all, 
So my husband and I have been trying to get pregnant for a few months now. Today i woke up and noticed I had some light brown spotting. It's been exactly 9 days after ovulation and 6 days before my expected period date. I am never late for my periods, they are always on time and exactly 28 days apart. Was wondering if anyone on here has experienced something like this? 
It's too early to take a pregnancy test so I was just going to wait it out until next Friday. I am just anxious 
Hope to hear some feedback ! Thanks, 
Jenna
