Hi, My gyn that there could be a link with some birth control pill's and dysplasia,especially if you have been using them for a long time.Depending on the strength and hormone's,there is a chance that could sort of add fuel to the fire,so to speak,and cause the dysplasia to be more persistant.It would not hurt to give your body a rest from the pill for awhile,just be sure to use protection.You may want to talk to your doctor about this,and try another method of bc to keep your period's regular.
