Be aware that this is a very unreliable method. Also, most women's cycles are somewhat irregular, so the calendar produced by Remind is very likely to get out of sync with the woman's body quite quickly. Anyway... here's a solution.

The average menstrual cycle is 28 days, not 30, although there are significant variations. My solution puts the first day of the cycle on the calendar; it would be trivial to add the last day also.
