If you want to begin charting your ovulation using your basal body temperature then a reliable thermometer is needed. By taking your temperature daily throughout your cycle you can confirm when ovulation has taken place and start to get an idea about the regularity of your cycle and when you are most likely fertile.
If you would like some ovulation tests and pregnancy tests along with the thermometer or a thermometer that reads to 2 decimal places, then please see product page for – Fertility/Ovulation Packs, Ovulation Thermometers (2 decimal places), Ovulation tests and pregnancy tests.

How to calculate your ovulation?
When trying for a baby, you probably ask yourself every cycle ‘when will I ovulate’. You can use an online ovulation calendar to calculate your ovulation date, but these just ask you to input your average cycle length. They will probably place your ovulation date around 14 days before your next period is due or halfway through your cycle which may be fine for many women. It is not helpful however, for women with irregular cycles or for women with longer or shorter than average luteal phases. The only reliable way to calculate your ovulation date and to predict when you may next ovulate is to chart your cycles.
To chart your ovulation you need to record your lowest body temperature each day and it is advised to take your temperatures’ first thing in the morning, when you have just woken up. You should take your temperature as close to the same time each day as you can e.g. if you wake for work at 6-7am, take it at 6-7am every morning before you get out of bed. It is advised to start recording your daily temperatures at the beginning of a new cycle (cycle day 1) i.e. the first day of your period. The temperatures’ before ovulation will be your pre-ovulation temperatures’ and your baseline.
A day or so before you ovulate, you will get an increase in a hormone called luteinizing hormone (LH) which will give you a positive ovulation test AKA LH tests or OPK if you use them. As luteinizing hormone levels increase it reaches its threshold level and an egg is released. Once the egg is released, your levels of progesterone will start to increase which warms the body. Once you have ovulated you should see a rise in your basal body temperature (BBT) on your chart. You need to see at least 3 high temperatures’ above your pre-ovulation range for 3 consecutive mornings to confirm ovulation. They should then stay high until your period arrives or until you give birth, if you are lucky enough to fall pregnant.
You can chart your ovulation easily with this digital thermometer and once you have your baby you can go on to use it as a baby thermometer. You will receive a free ovulation chart to help you get going which may be photocopied to use each cycle.

The mouth (oral cavity) is considered to be a reliable representation for human bodies core temperature. The thermometer needs to be placed underneath the tongue to the back of the mouth. It is advised that you keep your mouth shut for a minute or so before placing the Thermometer under the Tongue as mouth breathing can reduce the temperature reading. Do not drink any hot or cold drinks prior to taking your temperature as this will affect the accuracy of the reading also.
