Ideally: Your skin should be reassess at most several months(like on the order 12 weeks). Remember, there can be great variation in the nature of patients response(time wise), so do respond very quickly and some less so. If you've been using this regimen since October of 2014, then it sounds like it's time to reassess your acne management regimen.
