Heeeelllpppp! Bleeding?

Arod
Ok im freaking out im on my first month ttc and i am still trying to figure out my ovulation. I have had sex almost everyfay with a few days not having sex for a few weeks now. I would take ovulation tests every other day or so while on and off my period. My period doesnt come in for another 11 days and im pretty regular. Today i noticed spotting on my underwear and i have no idea what to think... Isnt it too early... Could it be implantation? And if ao why didnt the ovulation test show i ovulated or came close to it... Help please
