Chances of pregnancy after withdrawal bleeding

If a woman does not want to get pregnant after having sex, she needs artificial intervention to prevent the egg from being fertilized and becoming pregnant. Taking birth control pills is a better measure, because after taking birth control pills, the body will have withdrawal bleeding, which will cause the egg to be unable to survive. However, withdrawal bleeding does not mean that pregnancy will not happen 100%. Let’s take a look at whether the chance of pregnancy is high after withdrawal bleeding?

Generally, withdrawal bleeding will occur about a week after taking emergency contraceptive pills, and retrograde bleeding will occur 3 to 7 days after stopping the pills, which is equivalent to a menstrual period. The effectiveness of contraceptive pills can reach over 96%, but frequent use should be avoided as it can easily lead to menstrual disorders and irregular vaginal bleeding. If you are still young, avoid having sex too early and make sure to take contraceptive measures, such as using condoms.

The chance of pregnancy after withdrawal bleeding is usually less than 3%. If a woman suddenly stops taking birth control pills, the progesterone concentration in the blood will drop immediately, and the endometrium will lose the support of progesterone, which will cause "menstrual bleeding". This is the withdrawal bleeding caused by the decrease in hormone levels after stopping the medication.

1. Generally speaking, withdrawal bleeding is the same as menstruation, both of which are the result of the shedding of the endometrium in the uterine cavity. The only difference is that withdrawal bleeding is controlled by medication. However, whether it is menstruation or withdrawal bleeding, pregnancy can be ruled out.

2. If the amount of bleeding is heavy and lasts for more than three days, it can be regarded as a menstruation, indicating that the contraception is successful. If the bleeding is not heavy, it does not mean that the contraception is successful or not.

3. You can see a doctor for a blood chorionic gonadotropin test ten days after having sex, so that you can know accurately whether you are pregnant.
