is it working?

is the pill working even when I'm still bleeding? I mean, I started the birth control pills this month for the very first time but I'm still bleeding. I read it may be because my body is getting used to the level of hormones but is the pill working even now? I never skipped or being late with the pills, I'm taking it at the same time every single day. please answer I'm pretty new to this and I'm bit worried.
