Is it bad to wait a few days to restart birth control after being off it with sugar pills for your period Or do you have to wait to another week upon restarting another pack?

You start the new packet of pills the day after you take the last sugar pill, no waiting or delays - the bad thing about skipping a week is the very real possibility of pregnancy since a week of sugar pills followed by skipping another week of active pills means you may very likely ovulate before starting the new packet of pills.

You need to use back up (like condoms) until you have taken 7 active pills over 7 days to prevent pregnancy, if you start a new packet even 1 or 2 days late.
