Periods lasting ++ when starting the pill

Hello :)

So last year i broke up with a guy and i was on the pill with him not to get pregnant. Lately, i started dating a new guy so i started taking the pill like a week ago. But my period aren't stopping. Like they should last 5 days and im on day 7. I have "bleed" dark and smelly blood. Is that normal ? Is it going to last a long time ? Im seeing my bf tomorrow and we are super horny, im so sad that i wont be able to get some dick 😯😯 help please ??
