What does breakthrough bleeding mean?

Breakthrough bleeding is one of the side effects of birth control pills, but it does not happen to everyone. Many people report that the incidence rate is 1~13.5%, some think it is 2%, and some believe it is 0.2~16.4%, but the highest number is only 15~16%. So what does breakthrough bleeding mean? Let’s learn about it below.

The cause of breakthrough bleeding is actually quite simple. It is caused by malnutrition of the uterine wall leading to tissue degeneration. It has nothing to do with the occurrence of uterine cancer. There is no need to worry at all. The bleeding will naturally disappear during the course of taking the medicine. You can also change to another type of emergency contraception, or take 1.5 to 2 times the original dose, and the bleeding will stop. Another way to prevent bleeding is to stop taking the medicine immediately after bleeding occurs, and start taking it again from the fifth day after the bleeding starts. If the bleeding does not stop after taking the above measures, it should be considered that it is caused by other diseases. While changing to other contraceptive measures, a comprehensive examination must be carried out.

There are two types of breakthrough bleeding: those whose estrogen levels are low and remain at the threshold level for a long time often have intermittent bleeding, which lasts for a long time and the uterine wall repairs slowly; those whose estrogen levels are high and can maintain an effective concentration often have a long period of amenorrhea first, but because there is no ovulation and no estrogen resistance, the uterine wall is not strong and is easy to fall off on a large scale, resulting in subacute breakthrough bleeding with large blood strips.

Symptom 1: Irregular vaginal bleeding may be intermittent, with the amount sometimes more and sometimes less; there may also be symptoms of continuous bleeding, even up to 1 to 2 months.

Symptom 2: Delayed menstruation with menorrhagia: delayed decline of progesterone and irregular shedding of the uterine wall;

Symptom 3: Premenstrual spotting: Progesterone deficiency, insufficient progesterone secretion but normal progesterone life span;

Symptom 4: Mid- to late-term bleeding: A temporary decrease in estrogen before ovulation causes breakthrough bleeding; infrequent menstruation with excessive menstrual flow: normal follicular phase, short luteinizing cycle, cycle time less than 21 days; normal cycle with excessive menstrual flow.
