Implantation or period...

This is the beginning if the 2nd day of brown/even sometimes orange "spotting" it started on 12 dpo. It's such a small amount and is sometimes barely/not there. It's happened like 4 times and only when I wipe. I will post a picture when I have it again. What do you ladies think? I will probably test tomorrow morning with FRER if it stays the same or goes away.
