Is this normal like this to be on the pill?

I’ve been on birth Control for 3 months now, i just started my 3rd pack yesterday. It is my 6th day on my period, and i am still bleeding and that never happened to me before. Is that normal? Considering i just started my packet about 3 months ago. Well I’m in my 3rd month now. Is that normal for me to be still bleeding in my 6th day. I’m also cramping.
