The ';sugar pills'; contain no medicine. You can safely ignore them. That is, you don't actually need to take them. It's the pills for the other 3 weeks that contain the hormones to prevent pregnancy. So you only need to take those three weeks of pills, then you can skip taking any pills at all during the sugar pill week, then start again with the new month of pills at the end of the sugar pill week. The only purpose of the sugar pills is that it helps some women to have a routine of taking one pill each and every day. It's easier to remember to take a pill if you have to do it every day with no interruption. So you're fine--there's no such thing as being late with a sugar pill, because it doesn't do anything. Also, it's not made of sugar, that's just an expression.
