Confusion

Ok. I'm seriously confused. At 11dpo, I had spotting. Lasted tyre morning, then gone. Yesterday nothing all day, then dark red, what looked like clotted blood. Figured I would stay overnight or in the morning. Had some light spotting this morning (had a cup in). Now I'm back to brown. I'm 13dpo today. So confessed right now. Not sure if I'm out, or just delayed. This is my first cycle not on the pill. I don't typically have issues like this coming off birth control. But I am also 39. I'm just not sure what to think. If my period doesn't start full blown by Monday, I may test.
