Fertility Awareness Methods (FAMs) are a natural way to track your menstrual cycle and identify your fertile days. They are effective in identifying your fertile window and increasing your chances of conception.
There are several methods you can use to track ovulation at home, without the need for expensive tests or medical interventions. These methods rely on observing physical signs and symptoms that indicate when you are most likely to ovulate.
By keeping a record of these changes, you can gain a better understanding of your menstrual cycle. Let's explore some of the most popular natural ovulation tracking methods.
1. Calendar Method
The calendar method is one of the simplest ways to track ovulation at home. It involves keeping a record of your menstrual cycles over several months to identify patterns in cycle length.
To use this method:
- Start by marking the first day of your period on a calendar, digital or otherwise.
- Count the number of days until your next period begins. Record this as your cycle length.
After tracking several cycles, you can calculate your average cycle length and estimate when ovulation is likely to occur. This will automatically be calculated if you are using a period tracker app. Note that these are only approximations, though. Your actual ovulation date(s) might vary.
Typically, ovulation happens about 14 days before the start of your next period. However, the calendar method is less reliable for women with irregular cycles or those whose cycle lengths vary significantly from month to month (common for people with polycystic ovarian disorder (PCOD).
2. Monitoring Basal Body Temperature
Basal body temperature (BBT) is your body's temperature when you're fully at rest. By monitoring changes in your BBT, you can identify when ovulation has occurred.
To use this method, you'll need a basal body thermometer, which is more sensitive than a regular thermometer. Take your temperature every morning before getting out of bed, and record it on a chart. You may notice a slight dip in temperature just before ovulation, followed by a rise of about 0.2 to 0.5°C that lasts for several days. After ovulation, your temperature usually rises slightly due to hormonal changes.
This temperature shift confirms that ovulation has taken place. However, because the rise in temperature occurs after ovulation, this method is better for predicting future ovulation dates rather than identifying your fertile window in the current cycle.
3. Observing Cervical Mucus Changes
Throughout your menstrual cycle, the consistency and appearance of your cervical mucus change in response to hormonal fluctuations. The cervical mucus, by the way, is a type of vaginal discharge.
By monitoring changes in the texture and smell of the mucus, you can identify when ovulation is approaching. After your period ends, you may have little to no cervical mucus. As ovulation nears, the amount of mucus increases, and it becomes clear, stretchy, and slippery, resembling raw egg whites.
This type of mucus is more hospitable to sperm and helps facilitate their journey through the cervix. After ovulation, the mucus becomes thicker, cloudier, and less abundant.
To check your cervical mucus, wash your hands thoroughly and insert a clean finger into your vagina. Alternatively, you might find some after wiping or on your underpants. Observe the mucus's consistency and appearance, and record your findings.
4. Using Ovulation Predictor Kits
Ovulation predictor kits (OPKs) are home tests that detect the surge in luteinising hormone (LH) that occurs 24-36 hours before ovulation.
To use an OPK, you'll need to test your urine at the same time each day, typically in the afternoon or evening. Start testing a few days before you expect to ovulate based on the length of your average cycle. When the test detects a surge in LH, it will display a positive result, indicating that ovulation is imminent.
This method is more precise than calendar tracking or BBT monitoring but requires you to purchase test kits each month. It's mostly used by women wanting to get pregnant.
Did You Know?
Breastfeeding mothers can use the lactational amenorrhoea method (LAM) postpartum to track their ovulation. It relies on the natural infertility that occurs when a woman is exclusively breastfeeding. It can be effective for up to six months after childbirth if certain criteria are met.
