Menstruation is delayed for 4 days and there is a lot of leucorrhea

For some women, when their menstruation is delayed, they will think it is irregular menstruation. Actually, it’s not. Generally speaking, a woman's menstrual cycle is between 28 and 30 days. If it is delayed for a few days, it is actually normal. But if it is delayed for half a month, then you should be alert. If your period is delayed for 4 days and you have excessive vaginal discharge, it is recommended that you observe the condition of your vaginal discharge.

The average menstrual cycle for women is 28 to 30 days. It is normal for the menstrual cycle to be earlier or later than a week. If a woman of childbearing age with a normal sexual life has her menstruation delayed for more than a week, she may be considered pregnant.

The time between the first days of two menstrual periods. Most of the time it is 28 to 30 days, and 3 days earlier or later is within the normal range. The length of the cycle varies from person to person, but each woman's menstrual cycle must have her own regularity, otherwise it should be considered abnormal. The menstrual cycle is regulated by the interaction between the hypothalamus, pituitary and ovaries. The hypothalamus regulates the function of the pituitary gland, which in turn regulates the function of the ovaries. The endometrium undergoes cyclic changes under the action of ovarian hormones. The sex hormones produced by the ovaries in turn act on the hypothalamus and pituitary gland, affecting the release of gonadotropin-releasing hormone (Gn-RH), follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which is a feedback effect. When its release is inhibited, it is called negative feedback, and when it is promoted, it is called positive feedback. After the corpus luteum atrophies in the first menstrual cycle, the secretion of estrogen and progesterone decreases, relieving the inhibition on the hypothalamus and pituitary gland. Gn-RH produced by the hypothalamus promotes the secretion and release of FSH and LH.

Under the synergistic action of FSH and LH, the follicles in the ovaries gradually develop and mature, and the production of estrogen causes proliferative changes in the endometrium. After the follicles mature, the first peak of estrogen appears in the body. Increased estrogen secretion inhibits the production of FSH, promotes increased LH secretion, causes an LH peak, and triggers ovulation. After ovulation, the corpus luteum is formed and secretes estrogen and progesterone. Under their combined action, the endometrium undergoes typical secretory phase changes. After ovulation, estrogen levels temporarily decrease, followed by a second, lower peak. The large amount of estrogen and progesterone secreted by the corpus luteum reduces the secretion of FSH and LH through negative feedback, and the corpus luteum begins to atrophy. Subsequently, the secretion of estrogen and progesterone decreases, the endometrium loses the support of sex hormones, necrosis and shedding occur, and menstruation occurs. After the corpus luteum atrophies, the inhibition on the hypothalamus and pituitary gland is released, and Gn-RH is secreted again to start another menstrual cycle.
