Yes. Even missing one day of the pill will reduce the effectiveness of the pill. If you missed a week, the effectiveness of the pill increases a lot.

The advantage of the contraceptive pill is - it prevents unwanted pregnancy. The disadvantages are (1) you mustremember to take it each day and (2) some illnesses can reduce its effectiveness.

I have been on the pill for four years and have never had any breakthrough bleeding. I have also read that the longer you are on the pill the more it is effective. As previous anonymous said, the longer you are on birth control the more the effectiveness, provided you take your pills as scheduled. Breakthrough bleeding after years of use could mean that you might need to change the pill again because it may not be right for your system anymore. Contrary to what most people think, breakthrough bleeding is not an indication that the pill is any less effective. Good luck.
If you take your pill EVERYDAY at the SAME TIME the birth control pill is 97.9% -99.9% effective. If you miss a pill or switch times, you reduce the effectiveness.
