HELP! implantation bleeding or ovulation bleeding???

this may be tmi but i need help! today when i wiped there was blood on the toilet paper, but i’m not sure if this is from ovulation bleeding or if it is implantation bleeding and i am pregnant. i know i am currently ovulating right now because of my cycle so that very well could be it, but i’m worried that i may be pregnant since my boyfriend and i have had a couple close calls recently. does anyone know the difference between the two types of bleeding and if they look different/ what mine looks like??? thank you so much in advance!!!!
