A fertility calendar can help you track ovulation symptoms, along with your menstrual cycles and conception sex attempts. Fertility calendars sometimes, but not always, include tracking your body basal temperature. While you can track your BBT on paper, using a computer program or an online software program can make things much easier. The following websites offer free fertility calendars, with BBT charting options. is my personal favorite free fertility calendar website. I used this site to track my cycles for years. There is a free version, as well as a VIP version, but the free version includes more than enough to chart with ease. includes tons of fertility charting education, answers to common questions, an active support forum, and a huge gallery of fertility charts. While they do offer a fertility app, it does not sync with your online chart or include BBT information at this time. offer free fertility calendars that allow you to track as little or as much information as you like.

There is a free and paid online fertility charting option. The free online charting option only saves three months of charts, which may be a problem if you want to share with your doctor several months of charts (though I suppose you could print the charts before they disappear from the site.)
