risk of pregnancy

The risk of pregnancy generally refers to the chance of becoming pregnant during unprotected sexual activity. Factors that can influence this risk include the timing of intercourse within the menstrual cycle—most fertile around ovulation, about midway through the cycle—and the use of contraception. Without birth control, there's roughly a 15-25% chance of pregnancy from a single act. Certain health conditions, age, and reproductive health can also impact fertility. Understanding these factors helps in planning or preventing pregnancy, but individual risks vary and are best discussed with a healthcare provider.
