How do a woman naturally knows when she is fertile?

1. Basal body temperature (BBT) charting. A woman's BBT rises slightly after ovulation, and then falls again just before menstruation. By charting her BBT, a woman can identify her fertile window.

2. Cervical mucus changes. The consistency of cervical mucus changes throughout the menstrual cycle. Around the time of ovulation, cervical mucus becomes thin, clear, and stretchy, resembling raw egg whites. This type of mucus is more conducive to sperm travel.

3. Ovulation pain (mittelschmerz). Some women experience a sharp pain or twinge in one ovary around the time of ovulation. This pain can last for a few minutes or hours.

4. Breast tenderness. Some women experience breast tenderness or swelling around the time of ovulation. This is caused by the hormonal changes that occur during ovulation.

5. Increased libido. Some women experience an increased sex drive around the time of ovulation. This is also caused by the hormonal changes that occur during ovulation.

6. Mood changes. Some women experience mood changes around the time of ovulation, such as feeling more irritable, emotional, or anxious. These mood changes are also caused by the hormonal changes that occur during ovulation.

7. Spotting. Some women experience light spotting or bleeding around the time of ovulation. This is called mid-cycle spotting and is caused by the hormonal changes that occur during ovulation.

It is important to note that not all women experience all of these signs and symptoms of ovulation. Some women may only experience a few, while others may experience none at all. If you are trying to conceive, it is important to be aware of these signs and symptoms so that you can identify your fertile window.
