How Do You Know When You Are Ovulating? And How Do You Track It?

What Is Ovulation?

Ovulation happens around the midpoint of your menstrual cycle. It is triggered by the rise in the Luteinising hormone (LH) and causes the most mature follicle to rupture and release an egg, which then travels through the fallopian tube. An egg is viable for between 12 and 24 hours.

At this time, hormone levels change as the Oestrogen levels rise during the first part of the cycle, causing the uterine lining to thicken. Progesterone becomes the main hormone after the egg is released. These changes are driven by natural hormonal fluctuations throughout the cycle.

Physical Signs and Symptoms of Ovulation

The body may give you subtle but noticeable clues when you are approaching your fertile window. Not everyone experiences all of these symptoms, but it is possible to see a pattern when tracking these changes over a few months.

• Changes in Cervical Mucus: Cervical mucus changes can be observed as oestrogen levels increase. It tends to become clear, stretchy, and slippery. This helps sperm travel more easily through the cervix.
• Basal Body Temperature Change: You may experience a slight rise in the basal body temperature after ovulation. This is due to increased progesterone levels.
• Low Abdominal Pain or Cramp: Mittelschmerz refers to mild lower abdominal pain or a twinge. This normally occurs during the period when the egg is released from the ovary, although not everyone experiences it in the same way.
• Increased Sensitivity and Libido: The fertile period changes in hormones may also result in a heightened sense of smell and an increase in sex drive.
• Breast or Nipple Soreness: Due to hormonal changes before and after ovulation, breasts or nipples may be sore or tender. This symptom varies quite a bit, but it is fairly common during this time.
• Spotting: Light spotting may occur due to a temporary drop in oestrogen levels before ovulation

How to Combine Ovulation Tracking Methods for Better Accuracy

One or two of these methods may show you which days you are fertile. Using multiple methods improves accuracy in identifying and confirming ovulation. Cervical mucus can tell you when you are approaching the time of ovulation, and ovulation predictor kits (OPKs) can help you to detect the surge in the luteinising hormone (LH) that happens before ovulation. But basal body temperature indicates whether ovulation has occurred.

When using these techniques:

• Cervical mucus can help determine the fertile time.
• OPKs can help establish the fertile time.
• BBT indicates that ovulation has occurred.

The above signs of ovulation help to rule out anomalies caused by illness, stress or hormonal imbalance. This allows each individual's cycles to be better understood and for individuals to take control of their reproductive choices.

How to Measure BBT Accurately

When charting BBT, it is vital to take the temperature every morning when you wake, before getting out of bed, or eating/ drinking. It's important to use a digital thermometer with two decimal places. Take temperatures at the same time each day after at least 3 hours' sleep.

Factors That Can Influence Ovulation Cycles

Ovulation is a very sensitive process, and can be affected by a range of factors. Keep these factors in mind when you are analysing the tracking chart to ensure you're not misleading yourself.

• Stress & Emotional Tension: High levels of stress will delay or suppress ovulation altogether.
• Fever and Illness: A fever will cause the basal body temperature to rise, so the reading will not be accurate for ovulation prediction.
• Not Enough Sleep: Lack of sleep or a disrupted sleep schedule will cause temperatures to rise erratically.
• Alcohol and other lifestyle influences: Hormonal fluctuations can also be caused by high levels of alcohol consumption or drastic changes in diet and exercise routines.
• Travel: Travelling between time zones can disrupt your circadian rhythm and menstrual cycle.

When to Seek Professional Guidance

Although tracking your cycle will tell you a lot about your body, it should not substitute for a professional diagnosis, and certain trends may indicate you need to see a medical professional.

You will need to see a medical professional/specialist after several months of charting if your chart shows irregularity, shows no temperature shift (indicating you are ovulating), and cannot identify a clear pattern or explanation for temperature changes that will have an effect. You should consider taking a pregnancy test if your temperature has been elevated for 18 consecutive days.

Conclusion

Ovulation charting is an inexpensive, simple, non-intrusive method for monitoring your reproductive health. By measuring temperature, observing cervical mucus, and tracking bodily changes, you can create a chart to help you identify your fertile days. External factors, like a fever or stress, will sometimes be present, skewing the chart, but charting can help establish a baseline and see your typical pattern. Over time, charting is an incredibly useful tool for women seeking to take control of their fertility.
