I'm taking BCPs since past 2months, in my second pack I missed the 20th pill on wednesday, didn't remember to take it until next night. So I skipped the 21st pill too on thursday and considered my placebo week from wednesday to next tuesday. This changed my cycle(remembering the days dont concern me as already my pill cycle wasn't from monday, like it usually is for most people) Can I take my left out 2 pills from old pack in my new cycle to be started frm wednesday, i.e.23 active pills in total
