If you’re trying to get pregnant, understanding your ovulation cycle can greatly increase your chances of conception. Charting your Basal Body Temperature (BBT) can verify whether or not you are ovulating. Checking your Basal Body Temperature and understanding the changes that occurs during ovulation is crucial to increasing your chances of pregnancy. A Basal Thermometer can help you with this.

The Zoom Baby BBT Charting Pack contains:

1 x Digital Basal Thermometer
1 x Zoom Baby BBT Chart with full instructions


A Basal Thermometer is an important buy if you are planning on charting your basal body temperature (BBT) so that you can find out when you are about to ovulate.

What is ovulation and the process of conception?
As the saying goes a picture is worth a thousand words so we have included a short video which we feel gives an excellent short description of ovulation, including the whole process of conception (fertilisation and implantation) from the release of the egg from the ovary right up to the implantation of the fertilised egg at which point pregnancy has occurred, HCG is produced and the embryo starts to grow.

When a woman ovulates, a rise in body temperature takes place in order to provide a more fertile environment for conception. By monitoring when this temperature change occurs, you can determine when ovulation takes place in your cycle. Recording each day’s basal body temperature with a basal thermometer will help you predict ovulation!

What is my BBT ?
Your basal body temperature (BBT for short) is your resting body temperature ie your temperature when you are at rest.

When should I take my temperature?
You should take your temperature, orally under the tongue, every morning before you do anything else – even before you get up!! Just the act of getting up increases body temperature so keep the thermometer right by the bed. You should then write down the temperature recorded. The temperature rise (spike) takes place shortly after ovulation and will stay slightly elevated until you start your next period.

How do I measure my BBT ?
You will need to use a high accuracy clinical thermometer- the easiest to use is a digital thermometer that measures to 2 decimal places

Where do I put the thermometer to measure my BBT ?
For most women the best & simplest place to measure your BBT is under your tongue

How long do I leave the digital thermometer under my tongue ?
Most digital thermometers will beep when they have reached a stable temperature, making it quick and easy to know when to remove the thermometer. It usually takes around 1-2 minutes for this to happen.

What do I do with the basal body temperature results ?
You will need to chart the BBT results on a temperature chart , so that you will be able to see the pattern develop.

Is there anything I should not do when doing my BBT ?
Moving around, eating, drinking, smoking & even talking will raise your temperature, so make sure you do the temperature immediately upon waking each morning. If possible measure it while you are still “half asleep”.

What else can raise my basal temperature apart from ovulation ?
Illness if associated with fever will alter your resting temperature making interpretation of results problematic.

How does BBT charting help me predict my fertile time ?
Charting your basal temperature is helpful in determining whether and when ovulation occurs. Ovulation is the release of an egg (ovum) from the ovary and usually happens only once in each menstrual cycle. Conception can take place only if intercourse takes place immediately before , during or immediately after you ovulate.

By carefully recording your basal temperature when you first awaken, you will begin to notice a pattern of temperature fluctuation in your monthly cycle. The slight increase in basal temperature is an indication of ovulation or fertility.

What other bodily changes should I look for to know when I am about to ovulate?
The consistency of cervical mucus changes throughout the menstrual cycle. Usually after you finish your bleed you will have 3/4 days when you have dry days. The wetness then increases daily usually lasting about 9 days at which point the mucus will become plentiful, slippery, clear and stretchy. The best comparison is that it is like egg whites and at this point it is a good sign that ovulation will occur in the next couple of days. After ovulation occurs the mucus will again become more sticky less stretchy and then drier again.

    Bought this item and it arrived on a Monday. Very pleased with results until it stopped working three days later. Emailed Zoom Baby to inform them of the problem on the Friday, a reply from them on Saturday, and a brand new replacement arrived by Monday. Very impressed with excellent response. Thank you!

    This is exactly was looking for, even tells you when it is the best time to check your BBT. Before you get out of bed… Literally! It makes my daily chart app 100% easier as it is in Fahrenheit not in Celsius.

      Hi Barbara

      Thanks for taking the time to post a review of our BBT thermometer. We have always offered a Fahrenheit thermometer as standard as we think that charting is easier in Fahrenheit than in Celsius. However both methods are valid. We would be interested in hearing other views on this subject of course. 🙂

      Kind Regards

    This cheap basal thermometer is actually rather good! It arrived quickly and I was impressed to see that it came with full instructions and a fertility chart. The thermometer even has a handy, clear plastic case to keep it in. Ther thermometer works well and I have already started charting my cycle. I’m using this as well as Zoom Baby Ovulation tests, so hopefully between them I will have the best idea of when I am most likely to conceive.

    This thermometer is great value for the cheap price. If it helps me to take the guesswork out of my baby making process, even better!
