condomless sex, now yellow discharge

didn’t use a condom during sex saturday night. sunday i didn’t notice any discharge. today, monday, i wiped and it was sort of yellow. imagine right before you start your period and the discharge is tinged a dark brown. i did end my period saturday, so it could be that but again, it’s kinda yellow. this happened last time i had unprotected sex (w the same person) but i don’t have any itching and i don’t notice any smell. is it just bc it was without a condom?

like i said there’s no itching or smell and no pain and it’s happened before. up until like 2 weeks ago i’ve been using condoms and haven’t had this yellow issue.
