The Standard Days method is a kind of calendar method. It’s simpler than other FAMs, but you can only use it if your cycles are a certain length and regular.
How do I use the Standard Days method?
You can only use the Standard Days method if:
Your menstrual cycle is really regular (your periods always come at the same time).
Your cycle is never shorter than 26 days.
Your cycle is never longer than 32 days.
You’re okay with either not having vaginal sex or using birth control from day 8 through day 19 of each cycle.
To use the Standard Days method, you simply don’t have vaginal sex or use another method of birth control on days 8-19 of your cycle.
Most people using the Standard Days method use an app or have a special string of beads, called CycleBeads, that helps them keep track of their cycles. CycleBeads have 33 colored beads and a black rubber ring that moves from bead to bead.
Breastfeeding, a recent pregnancy, and hormonal birth control (including the morning-after pill) can mess with your menstrual cycle and affect how well the standard days method will work. Check out www.cyclebeads.com for more information.
