"i&#039;ve been on micronor for about 4 months, the first 3 months were perfect getting my period roughly a month apart at a time. this past month it seems i have gotten my period every other week! which is annoying!! my md said it may take around 3 months to regulate my cycle but it seems my body is doing the opposite. frustrated because i smoke and this birth control was the safest option for me. looks like things have to change.
