Birth Control Pills

I started taking sprintec birth control pills last month, and I thought it would be a good idea to skip the sugar pills to avoid getting my period. I started bleeding the next week anyways and it’s been about 6 days non stop.

What can I do to make that stop soon because I hear that it can last all month? (finishing the pack and then taking the sugar pills is my last resort) Should I just start the sugar pills for a week starting now?

Thanks in advance!
