Awesome except one detail

This app is very spot on with helping for the average nuvaring cycle. However, not all users allow for a menstruation week each month. Some wait every three months before taking a menstruation week, and there is no option for that. If that could be added, this app would be five stars. Until then, the app is unable to correctly follow my schedule. (In case Im confusing, basically every 3 weeks for 3 months I skip the menstruation week. This is currently not an option in the app therefore its helpless in my situation.)
Please change this so I can use it! :)
