Safe dates refer to a period of time during which it is considered safe for women to become pregnant. This term is commonly used in fertility awareness methods, such as the rhythm method or natural family planning, where couples track their menstrual cycles and other factors to determine when they are most likely to conceive. Safe dates typically take into account the length of a woman's cycle, the timing of ovulation, and any potential fertility risks based on her partner's sperm quality or medical conditions. By identifying safe dates, couples can plan for sexual activity during times when pregnancy is less likely to occur, either intentionally or as a form of birth control.
