how long until Levlen Ed will become effective?

User Profile
I have recently started taking cand was wondering how long until it will become effective as some people are saying a week and others a month. Also i started taking them on a Wednesday when my period began, so I took the Wednesday pill in the red section (which was 2 pills into this coloured section) as this is was I thought the doctor had told me to do but other people are saying I shouldn't have started on white tablets at all, that I should've gone straight to the beige ones... Have I done anything wrong?

Welcome to ehealthforum,
If you have started the tablets as instructed by your doctor and by following the arrow marks on the pack then you are safe. If in doubt, read the instruction leaflet or consult your doctor. The LEVLEN ED pack contains 21 small round beige hormonal tablets and 7 large white non-hormonal tablets. On the pack each tablet is marked with the day of the week on which it is to be taken. If you start on a Monday, Tuesday, Wednesday, Thursday or Friday, your first tablet should be white placebo one, while if you start on a Saturday or Sunday your first tablet should be a beige active one. Thereafter, you should take one tablet daily, following the arrows marked on the pack, until all tablets have been taken of the pack. Start the new pill pack at the scheduled time and be regular in taking the birth control pills at scheduled time daily. Each subsequent pack is started on the day after the last tablet of the previous pack. Withdrawal bleeding usually starts on days 2 to 3 after starting the white placebo tablets (last row) and may not have finished before the next pack is started. Start taking your next pack on the very next day after you have completed your last pack even if your period continues. This means that you will always start new packs on the same day of the week, and also that you will have your withdrawal bleed on or about the same day each month. Since most of the hormonal contraceptives start giving you effective protection after about 2-3 weeks of regular use, you are recommended to use additional protection if having intercourse during first few weeks of getting started on hormonal contraceptives.
Take care.
