Any thoughts?

Been ttc for 9 months now. I got my period 25-29 of August. Two days later I was spotting light pink. Normally if I spot after my period it’s brown due to old blood. And have had heavy cramping like my periods coming again and headaches. And I’m not supposed to ovulate for another week. I don’t know what’s going on. I’m just confused and tired of all these cramps 😩😩
