So confused, please give advice!

I'm so frustrated and confused. I'm on day 29 of my cycle, and this month I'm pretty sure I got 2 positive ovulation tests (day 15and 21), although if I were to question one it would be the first one. Now I've had spotting for 3 days, for the most part brown, but also has pink or red in it, and it has ranged from light to heavy. I don't think I have any other symptoms for either a period or implantation bleeding aside from cramping. Has anyone else had something like this?
