Are there first days meaning when you're bleeding or after you've stopped?
Hey Hannah, your cycle starts on the first day of your period, and ends the day before you get your next period. So by first five days, we mean the first five days of bleeding. Or, if you don't bleed for five days, this would mean the first five days of your cycle, starting on the first day of your period.
So technically, I'm fertile every day except the first five?
Does the length of your period factor in at all? My cycle is usually around 28 days but I have incredibly light and short periods.
Hi Casie, the first five days are just part of the time of your cycle you're infertile. To learn how to recognize all of your safe days, you'll need to confirm your fertile days with the daily observation of the primary fertility signs. You can confirm when you're fertile by tracking your temperatures and cervical fluid each day, and applying the 4 rules of using the Fertility Awareness Method as birth control (https://kindara.zendesk.com/entries/22043400-The-4-rules-of-using-the-Fertility-Awareness-Method-as-birth-control-explained).

If there's anything else I can help you with, please don't hesitate to let me know! Thanks again for writing us :)
Hi Jennifer, the length of your period doesn't affect the first five days rule - as long as you observed a temperature shift about 10-16 days before, you're safe the first five days of your cycle no matter how long your period is. Let me know if I can answer any other questions :)
