Ovusoft

For those couples who chart their fertility cycles and symptoms of ovulation, you may find Ovusoft to be a big help as it allows you to maintain your charts easily on your computer. Of course, you could always use an Excel spreadsheet or something too. However, Ovusoft does a lot of the work for you. It's makes it much easier for couples practicing Natural Family Planning.
