After your period, you will not have much cervical mucus and it is thick, cloudy, and sticky. Just before and during ovulation, you will have more cervical mucus and it is thin, clear, and stringy. It may stretch about 1 in. (2.5 cm) before it breaks.
For the 2-day method of checking your cervical secretions, ask yourself if you have secretions today and did you have secretions yesterday. For all days that you answer "yes" to one of these questions, it is likely that you are fertile and can become pregnant if you have unprotected sex. If you answer "no" to both questions on any day, you are not likely to become pregnant.
Home ovulation tests measure the amount of luteinizing hormone (LH) in the urine and display the results on a test strip or a small computer unit.
Combined (symptothermal) method
Many women have symptoms such as breast tenderness, swelling of the vulva, bloating, belly pain on one side, or increased sexual desire around the time of ovulation.
Fertility awareness is most effective when all the methods are used together. The number of unplanned pregnancies is 25 out of 100 women who typically use these methods.
If you have had a baby in the past 6 months or if you have an irregular menstrual cycle, it may be hard to use this method to know when ovulation occurs.
