Can I use Free Menstrual Calendar to avoid pregnancy?
You should not use Free Menstrual Calendar or any calendar based period tracker to avoid pregnancy, even if your cycle is regular.
Further, not every woman “fits” typical fertility patterns so calendar-based applications can not offer the reliability you need to avoid pregnancy. Stress, travel, changes in lifestyle and nutrition can also affect your menstrual cycle and may cause your cycle characteristics to vary from cycle to cycle.
Talk to your healthcare provider about the most appropriate contraception for you.
