late period

hi everyone. the last time i had sex was may 16 2021. we forgot to use a condom in the moment but he pulled out. i used a paper towel to wipe his cum off my stomach and crumpled it up but used the same towel to wipe off down there. i had a period a week after, another one june, & july. the last two periods i had were lighter than usual but lasted for 3 days. i’m now 2 days late for my period this month. is there a chance i’m pregnant?
