TwoDay Method

TwoDay Method

Women track their fertile periods by observing presence of cervical mucus (if any type color or consistency)      

How it works: 
Prevents pregnancy by avoiding unprotected vaginal sex during most fertile days.
Effectiveness to prevent pregnancy: 
96% with correct and consistent use. 86% with typical or common use. (Arevalo, 2004)
Comments: 
Difficult to use if a woman has a vaginal infection or another condition that changes cervical mucus. Unprotected coitus may be resumed after 2 consecutive dry days (or without secretions).
