Period ?

I haven’t gotten my period become I’m irregular.... I’m 16 years , a virgin, and a week ago I was working out and when I was done I went to pee, and I wiped and on I was a little redness/dark (kinda of) and it was so little bit,so I thought I was gonna start my period, so I drank tea and I waited for it but it never came . Idk what it was though. Any idea?

Thank guys !
