bleeding 4 days after losing virginity

I had sex for the first time and had no bleeding during but the morning after i was spotting. For 4 days I have been bleeding and i’m worried it’s getting heavier. My period isn’t for another 15 days. I am on the pill and we used a condom and the pullout method. Are there any chances for pregnancy and should i be concerned about the bleeding when my period is far along? please help!!
