The days of the week on the packaging are only to make it easier to take the pills and prevent missing a pill. They all contain the same amount of hormones, so it doesn't matter which pill you take on a given day. Today, Tuesday, you can take a pill marked as Tuesday, then Wednesday, Thursday, etc. The tablet marked as "Monday" - i.e. the one at the beginning of the blister can be taken at the end of the package, as the 21st - then the protection will be maintained.
It is important to take the tablets regularly - every day, at about the same time of day for 21 days. Then, after a 7-day break, start a new pack. Then protection will be provided.
