1 day like and I think I am spotting tmi

I am 1 day late going on 2 today. Had a little bit of brown spotting yesterday then this morning had brown spotting with a clear discharge idk why that is. 9dpo I had a sharp pain in my left ovary for about 5 seconds then it want away. Had mild cramping yesterday and none today. Could this be period coming or should I test soon? And if testing soon when should I test 7 days of period being late?
