How to Detect Ovulation Using A Basal Body Thermometer to time Intercourse
Timed intercourse is a natural method to increase a couple’s chance of conceiving by arranging the optimal time and frequency around a woman’s ovarian cycle. According to The Fertility Society of Australia, the fertility window starts 5 days before ovulation. Through the day of ovulation consistent with both the life cycles of sperm (5 days) and the egg (24 hours). Thus, identifying the day of ovulation in a woman’s menstrual cycle is the first step to optimising pregnancy likelihood, which can be more accurately predicted by using a Fertility2Family ovulation predictor kit (OPK) and using a basal body thermometer through and various methods of fertility monitoring.
Another initial step to improving a couple’s fertility is by having regular intercourses, approximately 2-3 times a week, to consider any irregularities that can affect the time of your ovulation, such as stress, medications, changes in physical activities, and lifestyle changes. This is also particularly beneficial in women who experience irregular ovulation due to certain medical conditions, for example, polycystic ovarian syndrome and hormonal imbalances, by implementing this routine in adjunct with fertility monitoring techniques such as checking your cervical mucus & cervix height, ovulation tests and using an ovulation thermometer for temping. Couples who are actively trying to have a child can increase their percentages of conceiving.
Fertility Charting and Basal Body Thermometer
Fertility charting, to put it simply, is the charting of your menstrual cycle. By collecting data that includes information about the day of your first menstruation in a cycle, length of menstruation, cervical mucus changes, and even basal body temperature, you may obtain important insights into your reproductive system. Therefore, fertility charting is essential for timed intercourse to happen by knowing the time of your ovulation. For such an important purpose, many women would be surprised to know that one of the easiest methods of fertility charting is through basal body temperature (BBT).
The biological reasoning behind taking a BBT is to detect the fluctuation of your basal temperature (temperature of your body at rest) throughout your menstrual cycle. The increase in progesterone just immediately after ovulation would have a warming effect on your body and contribute to an increase in your BBT. Plotting a graph of your waking temperature daily will help you to identify this slight jump in BBT during ovulation(usually less than 0.5 degrees Celsius) and may signal the perfect time to have intercourse.

Tips For Effective Basal Body Temperature Tracking
Ideally, it would be best if you started taking your temperature by using a BBT or ovulation thermometer on Day 1 of your cycle (first day of menstrual bleeding). You may indicate the time of your menstrual period with a note such as ‘Period’ and can help to calculate the cycle length and the time between ovulation and the next menstrual period.
Take your waking temperature daily after at least 5 hours of sleep, preferably at around the same time.
Basal body temperature is your body temperature at rest, so refrain from strenuous activities, eating, drinking or smoking before taking it.
Do not adjust or round off your basal body thermometer readings.
Use a basal body thermometer chart or graph to visualise your basal ovulation temperature pattern. After a few menstrual cycles, you will get familiarised with your BBT trends by identifying its highs and lows and can use this as an ovulation prediction for your next cycle.
Learn to interpret your basal body thermometer chart; your basal temperature would remain steady before ovulation. There is occasionally a slight dip on the day of ovulation, but there is usually an increase in temperature by at least 0.2 degrees Celsius within hours to 2 days after ovulation. Detect this raise in temperature, which signals ovulation, and it may remain consistent at that level until your next cycle begins. If the temperature remains high after 15 days with no menstrual period, this may indicate pregnancy has occurred. You may use a pregnancy test to confirm this suspicion.
Use a reliable basal body thermometer for fertility monitoring. A good fertility thermometer has high recording sensitivity and can detect changes as low as 0.01 degrees Celsius.
Fertility temping and using a basal body thermometer is an effective and highly efficient way to monitor a woman’s reproductive cycle. With its easy and relatively cheap application, women who are actively trying to conceive are recommended to use this method alongside other ways to recognize ovulation to detect the best days for well-timed intercourse. Another easy way to detect ovulation is by using Fertility2Family ovulation strip tests.
