For me, I usually get ewcm then a day or two later ovulation cramping and the day after that light brown spotting, but just a little bit. I'm not sure I would even notice if I wasn't paying such close attention to every little thing. A opk gets positive for me just before the cramping starts. It feels like menstrual cramping but smaller and very obviously to one side. After spotting my cm goes away, unless its a bfp month then it doesnt go away, just turns a little creamy. But, that's just me, I know there are an infinite number of variations.
