so i’m on the pill and had my period as normal

tuesday - friday well today I woke up and i’m still bleeding .. it never goes this long .. bright red still too .. I did have sex last night since yesterday was just old dry blood which is normal for my last day so what’s

going on? was it too rough for me to continue to bleed? i’m nervous this has never happened to me before. the toilet was a little red but everytime I wipe it’s bright red. I start my new pill pack tomorrow. also been on the pill for years so it’s not like my body’s getting used to it or anything
