How do birth control pills affect menstruation?

With the implementation of the policy of late marriage and late childbirth, modern couples have taken contraceptive measures before they have a pregnancy plan. Birth control pills are a contraceptive measure that is popular among young couples. According to scientific research in the medical field, relevant experts stated that emergency contraception affects women's menstruation, which is due to the effect of emergency contraception on the wall of the women's uterus. If you take short-term contraceptives for a long time, the uterine wall will soften, resulting in less menstrual flow; if you take long-term contraceptives for a long time, it is easy to have prolonged menstruation and increased menstrual flow.

The principle of emergency contraception is to inhibit ovulation and change the cervical mucus to make it difficult for sperm to penetrate, or to reduce the production of glycogen in the uterine gland ducts to make it difficult for the embryo to survive.

Generally speaking, emergency contraception taken by women is divided into high-efficiency, short-acting and birth control pills.

As for female friends, the medical community has also conducted surveys on some female friends. The data show that regardless of whether they are conventional high-effective, short-acting or contraceptive pills, many women do experience menstrual disorders after taking them.

The impact of emergency contraception on menstruation

1. Low menstrual flow

Because short-term contraceptives will inhibit ovulation, the amount of estrogen secreted by the female ovaries will immediately decrease. In addition, the amount of estrogen contained in the medicine is also small, so the female uterine wall will become soft, and the menstrual flow will become less and less.

2. Vaginal bleeding

Vaginal bleeding during the period of taking emergency contraception may be due to missed pills, resulting in insufficient certain female hormones. If vaginal bleeding occurs in the first half of the menstrual cycle, it may be caused by insufficient estrogen; if it occurs in the first half of the menstrual cycle, it may be caused by insufficient estrogen.

3. Long menstrual period and increased menstrual volume

Especially women who use long-term contraceptives in the first three months are prone to symptoms such as prolonged menstruation, heavy menstruation, shortened cycle time, and non-menstrual bleeding. If the menstrual flow increases again after taking it for more than three months, it is best to stop taking long-term contraceptives.

Generally speaking, the side effects of emergency contraception on women will gradually disappear with the discontinuation of the medication. If the side effects have not recovered within three months after discontinuation of the medication, you need to see a gynecologist immediately.
