How Taking Your Basal Body Temp (BBT) Daily Can Help You Track Ovulation & Get Pregnant
When you’re trying to get pregnant, taking your basal body temp and in turn tracking ovulation increases your odds of conception immensely.
Remeber that old saying: “knowledge is power”? Well, it reigns true even when you’re trying to conceive and especially when it comes to figuring out when you ovulate.
By tracking ovulation you are able to make sure that you’re doing the deed at the right time which means you are more likely to conceive in any given month.
If you’re going in blindly, with no clue when you ovulate then it can take even longer to get pregnant.
Not So Fun Fact: You only have 1 opportunity to get pregnant during each full menstrual cycle. The oocyte (egg) is only viable for 12-24 hours and if it is not fertilized within this time frame it dissolves back into the body.(1)
Which means you really only have 10-12 Opportunites to land a BFP (big fat positive) in a YEAR!

Basal Body Temperature: What is it?
Your basal body temp (BBT) is your bodies lowest temperature point in a given day (24 hour period). To get your basal body temp you need a specific type of thermometer (do not use a regular one BBT thermometers have a higher accuracy rate to a 10th of a degree) and make sure to get at least 4 hours of solid sleep.
Upon waking and before you move AT ALL (keep the thermometer close to your bed) take your temp and record the reading. For the most accurate results, you need to take your basal body temp at the same time every day.
Note: Physical activity leads to a higher reading as it makes your body heat up and reduces the accuracy of the reading significantly. Do not drink, get out of bed to use the restroom or even sit up as it will impact your results.
How to use Basal Body Temp (BBT) to get Pregnant
What you’re looking for when you start BBT charting is an elevation in your body temp, which occurs the day AFTER you ovulate.
Before you ovulate your basal body temp will most likely range from 97.00 to 97.70 Fahrenheit. The day after ovulation has occurred you will notice a slight spike in your temp by 0.5 to 1.0 degree. This spike lasts until your next period or until you get a positive pregnancy test.
Recording Your Basal Body Temp Data
Method 1: Apps/Online
If you’re using a period tracking app, most likely you’ve noticed an area dedicated to BBT charting.
All you have to do is input your daily temp and the app will create a visual chart for you, like the one above which is a screenshot taken from the Fertility Friend app.
It’s easy, and you’re unlikely to lose your data. It also helps the app predict ovulation for you, depending on how your app works.
Method 2: Pen & Paper
If you prefer to have a physical, hard copy of your BBT chart you can download a free printable BBT Chart here.
You will need to mark your own dots and connect them to see the dips & spikes.
Note: Your temperature can fluctuate, due to movement, illness etc. If your basal body temp does not stay elevated it’s unlikely that you ovulated. If you see spikes on odd cycle days i.e CD 5 then you can probably count that out as well.
Should You Start Tracking Your Basal Body Temp?
It takes time, patience and some serious dedication to chart BBT. You need to gather data for at least 2 months, preferably 3 to be able to accurately read and estimate ovulation day.
If you’re just starting out TTC I highly recommend trying OPKs (ovulation predictor kits) for a few months before resorting to charting.
Trying to temp, read and track can become overwhelming and cause unneeded stress. If you find that it is too much for you then discontinue charting and just stick with OPKs.
