the pill and periods

Mia
i started the pill three days before my period was due, which the doctor said was fine to do and that i would probably still have a period but it would be super light. It’s now 13 days after my period started and i’m still on it. i have also had unprotected sex with my boyfriend since and i have been on the pill but i’m not sure it’s safe as i’ve been on period. i could really do with some advice on what to do. do you think the pill still protected me and will my period stop?
