Using an Ovulation Calendar to Determine Fertile Days
A blog by Neway Fertility, January 13, 2015
At our New York Fertility Clinic, we see a lot of couples who need help determining when a woman is most fertile. While there are several methods to predict ovulation, keeping track of an ovulation calendar is the best way to determine the days when she is most likely to get pregnant.
Why? It's simple. A woman's best chance for becoming pregnant occurs four to five days before ovulation and ends 24-48 hours after the egg is released. That means she must know when ovulation is occurring so intercourse can be timed appropriately.
What is an ovulation calendar?
This simple formula that lets you know when ovulation is likely to occur, based on the date of your last menstrual period. For most women, ovulation occurs about 14 days from the first day of their period. So, if you start your period on June 1, you can anticipate ovulation to occur around June 14.
That doesn't mean you are only fertile on June 14. A woman's most fertile time is four to five days before ovulation until two days after it occurs. Therefore, if you started your period on June 1, your most fertile period would be from June 10 until June 16.
You can determine your fertile period each month using this method. Other natural ways to predict ovulation include:
- Recording your basal body temperature. Your temperature will steadily rise in the days leading up to ovulation, letting you know when to have intercourse.
- Observing cervical mucus. Three to five days before ovulation, cervical mucus will become clear and stretchy, indicating the egg is going to be released.
- Use an over-the-counter ovulation predictor kit. This tool will tell you when LH levels increase, letting you know ovulation will occur two to three days later.
