spotting

syd

i had unprotected sex on feb 7th during the end of my period. on the 14th (which would be 7 days later and 4 days after my period ended) i started spotting. this is the 3rd day ive been spotting. very very light. and i am also predicted to be ovulating right now as well. is this anything to worry about? im not on any birth control (im stupid i know)
