CycleWatch

This program helps you record the events of your menstrual cycle and uses that information to calculate and track fertile days and future cycles. The basic Windows interface feels a bit clinical but is quite handy. The only thing you might miss is a year-view calendar. It takes seconds to record any changes in your body. When your basal body temperature has been elevated for 18 days, CycleWatch prompts you to take a pregnancy test. In addition to the temperature, you can record the composition of cervical fluids, the position of the cervix, and the presence of luteinizing hormones. The manual offers brief instructions on how to keep track of the signs of your fertility cycle and what each of the signs means for fertility. You can e-mail the data to your doctor and predict your future cycles. Women who are trying to get pregnant without fertility drugs will get the most use out of this program.
