Here are the key signs of high fertility in a woman:
Table of Contents
Regular Menstrual Cycle
Having a regular menstrual cycle, typically every 28 days but can vary between 21-45 days, is a good indicator of fertility. Ovulation usually occurs 10-16 days before the start of the next period
Changes in Cervical Mucus
As you approach ovulation, your cervical mucus becomes clearer, more stretchy and slippery, similar to raw egg whites. This helps sperm swim to the egg.
Basal Body Temperature Rise
There is a slight increase in basal body temperature (taken first thing in the morning) on the day of or after ovulation. It remains elevated for about 11 days[1][3].
Heightened Sense of Smell
Some women notice their sense of smell becomes more acute right before ovulation
Breast Tenderness
Breast soreness or heaviness can occur after ovulation due to increased progesterone levels
Some women experience mild, brief pelvic pain around the time of ovulation
Tracking these signs, using ovulation predictor kits, and having sex during the 6-day fertile window (5 days before to the day of ovulation) can help maximize your chances of conception each cycle. However, irregular cycles, perimenopause, fibroids, endometriosis and other factors can impact fertility
Here are the key steps to accurately track your basal body temperature (BBT) to monitor fertility:
9 Symptoms Of Ovulation To Help Predict Your Most Fertile Time
Use a Basal Thermometer
Use a special basal thermometer that measures in 0.1°F or 0.05°C increments. Digital thermometers designed for BBT tracking are most convenient. Some options include:
- Digital Oral Basal Thermometer
- Basal Body Thermometer by iProvèn
- iBasal Digital Thermometer
Take Temperature at the Same Time Daily
Take your temperature first thing in the morning, before getting out of bed, at the same time each day. Set an alarm if needed. Aim to be within 30 minutes of your usual time.
Take Temperature Orally
Take your temperature orally and keep the thermometer in place for at least 5 minutes. Avoid taking it rectally or vaginally unless you can disinfect the thermometer properly after each use.
Record Temperature on a Chart
Note your temperature on a chart each day. You can use a printable chart, graph paper, or a fertility tracking app. Plotting the temperatures will allow you to spot patterns over time.
Get Adequate Sleep
Try to get at least 3 hours of uninterrupted sleep before taking your temperature for the most accurate reading.
Track for 3-4 Cycles
It may take a few months of consistent tracking to establish a clear pattern. Aim to chart your BBT for at least 3-4 complete cycles before relying on the data.
Consider Other Factors
Note any factors that may affect your temperature like lack of sleep, illness, stress, alcohol, or using an electric blanket. These can cause temporary spikes or dips in your BBT.
By following these guidelines, you can accurately track your basal body temperature to identify ovulation and your most fertile days each cycle when trying to conceive. However, BBT alone is not a reliable method of birth control.
