Understanding your body can bring clarity to questions about pregnancy and reproductive health. While it may seem like conception could happen at any time, pregnancy is only possible during a specific fertile window each menstrual cycle. Learning how this window works, and how it can vary, can help you make informed choices about your reproductive health.
At Pathways Clinic, we provide a professional, caring environment where you can learn more about your body and access guidance for navigating an unplanned pregnancy. We offer pregnancy testing, limited ultrasounds, and STI testing to ensure you have accurate, medically verified information.

Understanding the Fertile Window
Pregnancy can only occur during the fertile window, which typically lasts about six days each cycle. This period includes the day of ovulation, when an egg is released from the ovary, and the five days leading up to it. Because sperm can survive in the female reproductive tract for up to five days, intercourse during this time increases the chance of conception. Outside this window, pregnancy is unlikely.
How Ovulation Affects Timing
Ovulation is the key event that determines fertility. In a standard 28-day cycle, ovulation often occurs around day 14, but cycles can be shorter, longer, or irregular. Physical signs such as changes in cervical mucus or a slight rise in basal body temperature may indicate that ovulation is approaching. Once released, an egg typically survives 12–24 hours, which is why timing matters.
Why Calendar Tracking Isn’t Always Reliable
Using calendar calculations alone, sometimes called “period math,” can be misleading. Stress, illness, travel, and hormonal fluctuations can shift your period and ovulation from month to month. Even people with regular cycles may experience variations, meaning fertility-tracking apps provide estimates rather than medical confirmation.
Confirming a Possible Pregnancy
If you had intercourse during your fertile window and suspect pregnancy, medical confirmation is essential. Pathways Clinic offers free-of-charge pregnancy testing and ultrasounds to provide reliable results.
While an ultrasound cannot pinpoint the exact date of conception, it can estimate gestational age, confirm pregnancy location, and detect a fetal heartbeat to assess viability, offering a clearer medical picture than calendar tracking.
