Birth control and periods

So I started my birth control this month, and my period was late by 18 days, and now I'm on my 5th day of my period and it's still heavy and the cramps have been horrible. Normally it would be winding down by now but there's no sign of it ending soon. Is this normal? Or should I be concerned?
