WARNING GRAPHIC PHOTO

i had sex for the first time today, protected of course w a condom and he pulled out before he even came inside the condom.

when we were done there was no blood but a few hours later i went to use the bathroom and saw this on the tissue, AF is due in 5 days should i be worried??? is this normal? we did have oral sex about a week and a half ago and i don’t know if any sperm was on his fingers or if it got inside me. is this implantation?? or is it nothing to worry about? i am sore down there and it hurts to the touch.
