What color is the withdrawal bleeding?

Withdrawal bleeding also contains venous blood, so its color is still dark red. If withdrawal bleeding occurs after taking contraceptives, the amount is relatively small in clinical medicine, far less than the menstrual volume, and it takes about 3-5 days to stop bleeding on its own without the need for medication. If the withdrawal bleeding is caused by taking progesterone internally to induce menstruation, in clinical medicine, the amount of menstruation is basically the same as in the past, and the menstrual time is also the same.

Therefore, there is no need to worry when you have your period, just take good care of yourself during the menstrual period, keep warm, and change sanitary napkins frequently. When withdrawal bleeding occurs, if the color is bright red, it may be accompanied by other clinical symptoms. It is recommended to give appropriate examinations after withdrawal bleeding.

Withdrawal bleeding refers to a symptom. Vaginal bleeding usually occurs within one week after stopping the medication, which is medically called withdrawal bleeding, but it may be longer in some patients. The longer the amenorrhea lasts, the more withdrawal bleeding there is.

Practical significance of withdrawal bleeding

There is a certain amount of estrogen metabolism in the blood, uterus and ovaries, which causes the endometrium to proliferate. The central nervous system and the hypothalamus-pituitary-ovary have been basically established, but ovulation is not yet possible, such as some patients with amenorrhea and immature hypothalamus-pituitary-uterine-ovarian axis, polycystic ovary syndrome, etc.

(2) If menstruation does not occur after injection of corpus luteum copper (other than physiological pregnancy), it indicates that blood pressure and uterus may be abnormal. The secretion of estrogen in the uterus and ovaries is insufficient to cause the proliferation of the endometrium, so it cannot bleed. Supplement congenital occlusion of the cervix and vagina causing latent amenorrhea. Further investigation is needed to clarify which reason it is.

(3) Withdrawal bleeding is also called "replacement menstruation" and is the same as menstruation. It is often called replacement menstruation because the bleeding days are controlled by medicine instead of being calculated according to normal conditions. The next menstrual period can be calculated as a menstrual period based on this replacement menstruation, and the next menstrual period will be based on this time.
