Charting Your Fertility Pattern

Looking to increase your likeliness of getting pregnant? Familiarize yourself with methods that will allow you to predict your fertility days.

Basal Body Temperature Method – Basal body temperature is your temperature at rest as soon as you awake in the morning. A woman’s basal body temperature rises slightly with ovulation. So by recording this temperature daily for several months, you’ll be able to predict your most fertile days.
Basal body temperature differs slightly from one woman to the next. Anywhere from 96 to 98 degrees Fahrenheit orally is average before ovulation. After ovulation most women have an oral temperature between 97 and 99 degrees Fahrenheit. The rise in temperature can be a sudden jump or a gradual climb over a few days.

Cervical Mucus Method – This involves being aware of the changes in your cervical mucus throughout the month. The hormones that control the menstrual cycle also change the kind and amount of mucus you have before and during ovulation. Right after your period, there are usually a few days when there is no mucus present. As the egg starts to mature, mucus increases in the vagina, appears at the vaginal opening, and is white or yellow, cloudy and sticky. The greatest amount of mucus appears just before ovulation. During this period, it becomes clear and slippery and can sometimes be stretched apart. This is when you are most fertile.

Calendar Tracking Method – Your past menstrual cycles will work as a guide for estimating your fertile times. In order to track your menstrual cycle and to identify your expected ovulation follow the step by step process below:

Step 1: Plan on tracking your menstrual cycle for 8 to 12 months.

Step 2: Day 1 will be the first day you start menstruation.

Step 3: Pick the longest and shortest of the cycles from your monthly tracking.

Step 4: The first day of your fertility period is determined by subtracting 18 days from the length of your shortest cycle. If 26 days was your shortest menstrual cycle, take 26 and subtract 18 to come up with the number 8. This means that the first day of your fertility window starts on the 8th day of your cycle.

Step 5: The last fertile day is determined by subtracting 11 from the length of your longest cycle. If 32 days was your longest menstrual cycle, take 32 and subtract 11 to reach the number 21. This means that the last day of your fertility period ends on the 21st day of your cycle.

The time in between these is considered your fertility window.
