If you’ve been pregnant recently, and the pregnancy has ended, you can use Clue Birth Control if you have had at least 3 eligible cycles (4 periods) since the end of the pregnancy.
If you were or still are breastfeeding, you can use Clue Birth Control as long as you have had 3 eligible cycles (4 periods) since the end of your pregnancy. These cycles must be between 20-40 days long, with a difference of 9 days or less between your shortest and longest cycle.
