Basal temperature chart for ovulation

One of the methods to find out when a woman is having ovulation is measuring the basal temperature.

Measurement of basal temperature in determining ovulation

The basal temperature is measured after a 5-hour sleep, this is the temperature measured between the mucous membranes, and not between the folds of the skin. And therefore the method of measurement in the armpit is not good. It is measured in the mouth (under the tongue of 5 minutes), as an option - in the rectum or vaginally (3 minutes).

The basal temperature should be measured at the same time in the morning (within half an hour), one thermometer is used, the measurement starts from the first day from the beginning of the month. All the results a woman writes down by plotting. It is important to take into account all the factors that can make unreliable measurements (inflammatory processes with hyperthermia, both local and general, taking sleeping pills or hormones, severe stress and exercise, taking large doses of alcohol).

Basal temperature before ovulation, during and after it

To know what basal temperature was before ovulation and what basal temperature at the onset of ovulation, you need to draw up a temperature graph, connecting all the temperatures for all the days of the cycle. In this case, before ovulation, the graph is usually even and without uplifts. The basal temperature before ovulation can even be slightly lowered (as before the menstrual period).

And with the onset of ovulation, three days on the temperature chart rises, with two days - more than 0.1 degrees, and another day - more than 0.2 degrees (compared with the previous rates). It is important to remember that 6 days before ovulation, there should be no lifts on the chart at all (a straight line), and the ovulation line does not appear on the day, but 1-2 days after ovulation. Next is a graph of the second phase of the cycle, which is higher from the first by 0.4 degrees, it should not be less than 10 days.

Basal temperature at conception

If you look at the graph of basal temperature, then at conception it is best to use those 3 days of temperature rise (the beginning of its rise after the first phase). But if the graph is flat, there is no difference between the first and second phases of the cycle, then this menstrual cycle is called anovulatory (in it, ovulation does not occur, and hence conception is impossible). Such cycles in the year can be up to 2, but if this happens all the time, then when planning pregnancy, you should contact a gynecologist.
