Can I start the Fertility Cleanse Late?

It is fine to begin the Fertility Cleanse 2-3 days after your period ends. If it is going to be longer than that before you receive the kit, it would be best to begin the Fertility Cleanse Kit on the upcoming menstrual cycle. If you want to begin a few days late, go ahead and overlap both phases in the middle (day 17, 18 and 19). This means you will be taking all the products for those few days.
