Ovulation spotting

CD 15 and haven't gotten my high nor peak on ovulation test yet. However today, I noticed I had slight spotting when I wiped. My cm had a tint of pink in it and it wasn't clear/egg white. I've never had spotting during my ovulation week before. 
My question is, does this mean I'm ovulating even though tests read otherwise? I know sometimes it's best to just go off of what your body is telling you and not the tests. I've always thought that if you spot during ovulation that's when it's the best time to BD. Is this true? Or does it mean I'm going to ovulate soon.
Thanks in advance for your help and input.
