Implantation bleeding

Alright, I had sex with this guy 2 weeks ago and the condom broke. It was the day after my period. I still had a little bit of light pink spotting. I had sex with him last weekend also with a condom, the day before Glow predicted my ovulation day.

Yesterday I had a small amount of light pink spotting on the toilet paper. Nothing else. Just the once. My period isn't supposed to start till next week.

Could this be implantation bleeding? If so, when should I test? Would that mean I ovulated early? Should I go by dpo or when the condom broke?
