It's important to take a systematic approach and fill-in your data on a daily basis. Try to make as many observations as you can every day, with the recommended minimum being basal body temperature and cervical mucus.
Take your basal body temperature every day, at the same time, before getting out of bed. Write it down to two decimal places and mark the time (with a 30 minute approximation.) Make sure you know how to correctly measure your basal body temperature. At OvuFriend, you can set the time you usually take your BBT by selecting the box "set default" . Remember, though, if you measure your BBT at a different time one day, you will have to manually select the correct hour from the list.

Apart from taking your basal body temperature, make sure you check your cervical mucus. Unlike temperature, you should check your mucus several times a day (at least three), preferably at different times of the day (in the morning, at noon, and in the evening). Always note down the most fertile mucus observed on a given day. At OvuFriend, you can choose from five types of mucus. Make sure that you know the different types of mucus, how to recognize them, and how to record your observations. Checking mucus is very easy and takes only a moment.
You may also opt to check your cervix, its position, texture and opening. (How to make observations of the cervix?) If you're unable to note all three of the parameters, enter only the ones that you can. For example, if you can sense easily that the cervix is low, but you cannot tell if it is open or closed, enter only its position.
In the menstruation/spotting box, note any instance of spotting or bleeding (How to distinguish spotting from menstruation?) The first day of menstruation is the first day of your cycle. Once you note menstruation has begun, OvuFriend will start a new cycle for you.
Enter the approximate times of intercourse, whether in the morning or in the evening. If you have intercourse two or more times in one day, choose the option: in the morning and in the evening. OvuFriend will use this informaiton to calculate your chances of getting pregnant during this cycle. The time of intercourse can also be a vital piece of information for you and your doctor, in order to determine whether it's optimal toward increasing your chances for conception.
Remember that the more observations you make, the better OvuFriend can determine your fertile days and help you increase your chances of getting pregnant.
