Most girls and women note that during the period of expected ovulation (which should occur on the 12-14th day of the 28-day menstrual cycle) and for several more days after that, the chest hurts. Why is this happening and how to explain it?
Some women notice unpleasant pain in the chest during ovulation and a few days after it. These pains can differ significantly in intensity in different women, but the symptom itself may indicate that ovulation has occurred, and the mature female reproductive cell (egg) is ready for fertilization.
Some women really use this sign, trying to "catch" the days of probable conception, because the soreness of the breast tissue, their slight increase in size is explained by changes in the hormonal profile in the woman's body during the menstrual cycle. Like the tissues of the internal genital organs, especially the mucous membrane of the uterus, the tissue of the mammary glands changes cyclically, under the influence of female sex hormones - estrogens (which prevail in the first half of the cycle and actually prepare ovulation) and progesterone (promotes the introduction of a fertilized egg into the mucous membrane of the uterus and progression the onset of pregnancy).
But the mammary gland, in addition to the glandular tissue, also includes connective tissue septa, which divide it into lobes, and neurovascular bundles, which are involved in the blood supply and innervation of the gland tissue. Therefore, with the temporary development of the glandular component, full stretching of the connective tissue does not occur, and the passing vessels and nerves are compressed, which explains the special sensitivity of the mammary gland after ovulation.
All these changes are explained by the influence of estrogens, which, immediately before the moment of ovulation, reach their peak value in the woman's blood, respectively, the second peak falls on the time of a short-term increase in the concentration of estrogen 4-5 days before the expected date of the next menstruation. But in this case, most gynecologists and their patients prefer to say that a woman has signs of premenstrual syndrome (PMS).
Therefore, the appearance of pain in the middle of the menstrual cycle, 12-14 days after the onset of the next menstruation (regardless of the duration of the menstrual bleeding itself), indicates that ovulation, with a high degree of probability, has occurred.
