Why am I spotting ? Can I be pregnant?

3days ago We didn't have sex but for the first time he just got in me very brief for only one inch i guess and I wash myself immediately, but lm spotting for 2days like in brown and it's time for my ovulation It can't be my period .he also fingered me, so should I worry about infection or scars? Or could I be pregnant from that brief touch of precum?
