unusual bleeding...help me

so i take the pill and a couple days ago i went out & got drunk with some friends & i don’t really remember what all happened (i might have had sex but not sure & i’m a virgin - or i was idk) since then i’ve been bleeding a little bit but only when i pee. i’m supposed to have my period in about a week. i’m not sure if this is just regular spotting or what it is but it has me a little worried. any comments or opinions would be appreciated :)
