How does TwoDay Method work?
A woman checks for secretions daily as soon as her menstrual bleeding stops. Secretions are anything that the woman perceives as coming from her vagina, except menstrual bleeding.
A woman may feel moisture at the opening of her vagina or see secretions on toilet paper, her underpants, or her finger.
Secretions generally start a few days after her period stops. Once secretions start they continue for several days in a row followed by days without secretions.
If she does not notice secretions today AND yesterday (two consecutive days without secretions), pregnancy is unlikely.
If she notices secretions either today OR yesterday, pregnancy is likely today. She must avoid sex on those days to avoid pregnancy.
