Ovulation spotting?

Hey ladies. Please help!

So I’ve been using opk every day and have not yet ovulated this cycle. I’m currently on cd 17 today, which is when I ovulated last cycle. And today I had some light spotting (only when I wipe - sorry tmi). And mild cramps. This hasn’t happened to me before. I’m working all day and cannot test for ovulation until like 9pm. Could it be ovulation bleeding? And if so, does ovulation bleeding happen before, during, or after ovulation? In other words, does it mean I’m ovulating, about to ovulate, or is it too late? Could I have missed it? I’m freaking out because I don’t wanna miss my ovulation this cycle. We haven’t BD since 3 days ago because we’ve been so busy and tired. I’m definitely going to try to today. But I’m kinda scared that I somehow may have missed it?

Has this happened to anyone?
