I have had my period for about 10 days now, I was off birth control for about two weeks, and when I went back on it I started taking a different brand than I usually use. Should I stop taking my pack and wait until Sunday to start the new pack ( which is my original brand of pills I take) so the bleeding will stop, or do I continue with the pills I have now and finish that pack? Also will the bleeding continue until Saturday which will be the last pill I take?
