How It Is Done continued...
If you want to become pregnant, have sex every day or every other day from the day you see your cervical mucus becoming clear and stretchable until the day it becomes cloudy and sticky. Do not test your mucus right after sex, since semen may be mixed with it.
If you do not want to become pregnant, do not have sex or be sure to use another method of birth control from the day your cervical mucus becomes clear and stretchy until the 4th day after it becomes cloudy and sticky.
Another 2-day method of checking your cervical secretions can be done. Every day of your cycle, 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.
If you are using a home ovulation kit, follow the instructions on the kit exactly.
Combined (symptothermal) method
This method uses some of the other methods all at once to tell you the most fertile days of your cycle. You check your basal body temperature, the changes in your cervical mucus, and a hormone test, and you watch for signs of ovulation (such as breast tenderness, abdominal pain, and mood changes). You may have any of the following physical signs of ovulation:
- An increase in sexual desire
- Pain in your lower belly on one side or the other (called mittelschmerz). This pain can be sharp or dull and usually lasts from a few minutes to a few hours. It occurs when the egg is released from the ovary on that side. The ovaries usually switch releasing an egg each cycle, so pain occurs on the side the egg is released from during that cycle.
If you do not want to become pregnant, do not have sex or be sure to use another method of birth control for 5 days before ovulation may occur and on the day of ovulation.
