Your skin at the moment is really clear and looks healthy. I personally wouldn't advise you to use the acne.org regimen and that's from personal experience. It's not that it didn't work for me, but when you have very mild acne, is adding BP to your face worth the implications? You're going to have really dry and flaky skin for the first two weeks and I kid you not, it's not an exaggeration how flaky it actually gets. Also if you were to come off the regimen, your skin could end up looking worse than it does now.
Those that say 'go for it' are usually the ones that have fully adapted to it and are dependent on the regimen in order to maintain clear skin - which is of course not their fault, their form of acne requires antibacterial treatment. Yours seems to be very tame and by treating your skin kindly, I think you could clear those blemishes up quickly and safely.
Also, you're 14. Don't go damaging your skin at this point by using BP, let your skin grow and repair itself. A lot of people here have adult acne that is persistent, try work out your skin type and be gentle to it for now. Trust me 
Actually I agree a lot with this statement. Your acne is mild and you are still young. Trying to address your minor acne with a less harsh method IS a reasonable consideration.
i started with the regimen before 4 days my skin got extremly dry and red during the day i apply moisturizer few times , is it normal and will it always be that red ? t
Yes, Pepe10, unfortunately this is a normal reaction when first starting the regimen, and it usually last anywhere from 3 -8 weeks or so. Just make sure you arent using too much BP in the early weeks. Start with a small application (pea size) once a day for a few days, then the same amount twice a day, and then slowly build up your BP application until you are using the full recommended amount.
But there is no getting around the redness and dry/itchiness until your skin adjusts to the BP. But it DOES get better. Patience and persistence. Good luck my friend!
