Fertility Chart Key

Your cycle begins on the first day of your menstrual period. Start a new chart on this day.

Fill in the days of the week, leaving Saturday and Sunday blank for easier viewing.

Your temperature can change dramatically if you take your temp at a different time each morning. Try to be consistent. Record that time here.

Start counting "post ovulation" days after your peak day has been reached.

Circle your temperature each morning. Then draw a connecting line from yesterday's temp to the new temp. After you've had a significant jump in temperature, go back to your last low temp and count four temps backward. Draw a "cover line" (horizontal line going from left to right) through the temp above that fourth low temp. See the book, Taking Charge of Your Fertility, for more information about drawing cover lines.

This is a short description of the consistency of your cervical fluid for each day.
P = period
S = sticky
C = creamy
E = egg-white

Your peak day is the last day of true egg-white cervical fluid. It signifies the day when you were most fertile.

This relates to the texture and feel of your cervix.
F = firm
M = medium
S = soft

This relates to the position of the cervix in the vagina. Draw a small circle in the upper part of the box for a high cervix, and a circle in the lower part of the box for a low cervix.

Record what you felt at the opening of your vagina throughout the day. Some of the sensations you might feel include, dryness, dampness, moistness, and wetness.

This is a more detailed description of the cervical fluid you find while wiping or by checking your cervix (you should never alternate between the two, as your findings will be different in different locations; stick to one method throughout the cycle) Some descriptions include sticky, scant, lotiony, creamy, slippery, clear, wet and egg-white (also known as EWCM).

Be sure to record when you have intercourse.

Note whether or not protection was used during intercourse.

Be sure to record when you have been sick, when you stayed up particularly late, etc. as this can change your temperature readings.
