Using trackle with PMOS (formerly PCOS) can be particularly helpful: Since trackle does not calculate on a calendar basis, but recalculates every day using your data and personal inputs, you can use trackle for all types of cycles, even very irregular ones. trackle helps you understand whether or not ovulation has actually occurred.
You can also discuss your trackle cycle records with your doctor to see if you can identify any patterns. Importantly, trackle does not replace a visit to the doctor—it simply provides an additional way to track your cycle.
