Am I protected during the first week of a new 21 day pack? Watch
Once you've completed a full 28 day cycle (which you have), you should be protected all the time as long as you maintain the 'all on time' regime.
BUT, please remember that no pill is 100% protection, and there are lots of factors that could leave you at risk to some degree. Reading the information leaflet that comes with your pill should give you more information on this, however, the leaflets are always written with worst case scenario in mind.
