O day help

Here's the deal. I thought I was supposed to ovulate this past Sunday, which is cd 14. I'm very regular with my cycles. I didn't use opk's or bbt just cm and cp. Saturday night I had light spotting. I'm pretty sure it was ob. I also had some on Sunday but just a little. It was brownish/red in color. Did I o Saturday or Sunday? I'm just trying to figure out what dpo I am. Thanks ladies

possibly Saturday morning.

Thank you. That's what I was thinking but just wasn't quite sure. I have 2 children already but I have never noticed ob or the cramping and things that I'm noticing now so I didn't really know what to think. Lol thank you for your input.
