Great for tracking everything !!

This app has a lot of ways of tracking fertility and even journals and week to week up dates. I am not TTC until January but it’s better to start early with tracking and this is the perfect app. There are also articles and question forums of people who are currently in the journey themselves. Love love love !!!
