Implantation bleeding?

OK... I had sex with my fiancé the day before my ovulation. We were both aware of that. But anyway, it’s all said and done now. Fast forward to yesterday and the day before; I’ve been bred red almost pink bleeding just a little bit accompanied by brownish cm.

It’s kind of bothering me. I have two weeks till I can test. I’m just a little worried that was, in fact, implantation bleeding. We had sex last month two and I had a positive then two negative tests. It’s very strange. So, ladies, I’m asking you has anyone else experienced this? and when in their lives did you experience this?
