The feeling of bloating in the abdomen without successful implantation is considered to be related to the imminent onset of menstruation. For women who have not succeeded in getting laid, the corpus luteum formed after the follicle is discharged gradually shrinks and the estrogen and progesterone produced gradually decreases, then the pelvic tissues will gradually become congested under the action of hormones, and then there will be a feeling of abdominal bloating and other discomforts, so there is no need to be too nervous, and the symptoms can be relieved after the menstrual period is cleared. For premenstrual women, pay attention to warmth, pay attention to rest, do not do too strenuous exercise, keep a happy mood, if the symptoms continue to be unrelieved, it is recommended to go to the gynecology department of the regular hospital, complete ultrasound and other related examinations, to determine the cause of the cause of the disease in the guidance of the doctor to actively treat.
