"An ovulation calendar helps you tracks the optimal time to achieve pregnancy"
The first morning of menstrual bleeding (not spotting) is the start of each cycle. Indicate menstruation with a ✔ on the chart, starting on day 1 of cycle.If spotting occurs mark this with a ✘ (see sample chart).
Insert date of month in space provided
Use any centigrade thermometer. A digital thermometer may be easier to read.
Each morning, before getting out of bed or eating/drinking, place your thermometer under your tongue. If using a nondigital thermometer your temperature should be taken for 3 minutes. Do this every morning even during menstruation
Record your temperature reading on the chart by placing a dot at the intersection of the appropriate temperature and date lines. Join the dots with a straight line (see sample chart).
On the chart, mark the days you had intercourse by circling the temperature dot (see sample chart).
It is important to start a new chart on the day menstrual bleeding begins.
Your doctor may order a blood test for serum progesterone to confirm ovulation. This is best done 7 days after your temperature rises.
Your temperature chart is an indirect predictor that cannot confirm the exact day of ovulation. It is useful after the event has occurred.
Intercourse can take place at any time during the circle, but at least every second day during the fertile phase. Over a number of cycles a pattern of your fertile time may become more apparent.
