Implantation bleeding??

Shannon • Momma of 1 beautiful girl and a baby boy on the way 💙

So last night after I went to the bathroom (number 2 sorry tmi), I wiped once and there was a little bit of spotting. Light brown and three spots in a row. It has been over 12 hours since and I’ve had nothing else happen. I was 11 dpo at the time of spotting. Was this implantation bleeding or is my cycle being weird? I’m due to start on Sunday. Anytime before that I’ve had spotting, once it’s started it doesn’t stop. Help!!
