Are ovulation tests reliable? Is it possible that I may not ovulate in certain months?

Yes, ovulation tests are reliable. It is possible for some women to not ovulate every month, especially if they have longer cycles. It is important to track the length of your cycle and consider using a thermometer to monitor ovulation. Using an app like FLO can help determine the length of your cycle and pinpoint the best time for ovulation testing. Remember to use concentrated morning urine for accurate results, and typically ovulation occurs between days 10 and 19 of a cycle, with day 1 being the first day of menstruation.
