The easiest way to find out, free of charge but a little restrictive, is the thermal curve, which consists in taking one's temperature every morning before setting foot on the ground.
The progesterone secreted by the corpus luteum is called thermogenic, that is, it raises the temperature above 37 ° C. The day of ovulation, in the middle of the cycle, is the most low of the temperature which precedes 24 hours the thermal shift.
Then, the temperature curve remains increased by 0.5 ° C plateau during the luteal phase, that is to say, normally for 12 days, then the temperature decreases if there is no pregnancy.
The thermal curve confirms ovulation, and specifies the life of the corpus luteum, but not its quality that can be evaluated by the dosage of hormones.
