Will taking birth control pills affect menstruation?

Birth control pills are a common contraceptive measure and are also quite common in daily life. Birth control pills mainly contain hormones that prevent pregnancy. The role of birth control pills in life is mainly to prevent some female diseases and some pregnancy measures. Birth control pills also have many side effects, mainly some common factors of early pregnancy, such as nausea, vomiting, dizziness, fatigue, increased vaginal discharge, and menstrual disorders and decreased menstrual flow.

Many contraceptives can affect menstruation, including some effects on menstruation, which are mainly some reduced menstrual volume and amenorrhea, which means that the endometrium cannot grow normally, and may even cause some bleeding conditions and some sudden vaginal bleeding.

1. Pregnancy-like reactions are common, accounting for about 50% of the number of people taking the medicine. Symptoms are usually severe at first, then become mild and gradually disappear, which may be related to the body's gradual adaptation. A small number of people experience mild early pregnancy-like reactions in the early stages of taking the medication, such as nausea, dizziness, weakness, loss of appetite, fatigue, vomiting, etc. It usually occurs within 1-2 weeks of taking the medicine. The reason is that the estrogen level is temporarily excessive, causing water and sodium retention in the body and gastrointestinal dysfunction. Generally, after taking the medicine for 2 to 3 months, the reaction will disappear or alleviate naturally. Scheduling the medication time before going to bed at night can make the daytime reaction lighter. For those with more severe reactions, vitamin B6 can be taken, 20 mg each time, 3 times a day. If there is still no relief, you can consider changing your contraceptive pill and choose one with lower estrogen content. 2. Increased vaginal discharge is often caused by long-acting oral contraceptives. Because this type of drug has a high estrogen content, excessive estrogen affects the secretory cells of the cervical endometrium, causing them to secrete more vigorously and causing an increase in leucorrhea.

3. Breast pain is caused by estrogen stimulation to the breasts.

4. Menstrual disorders include: ① Decreased menstrual volume or amenorrhea. This situation often occurs after taking short-acting contraceptives. This is because the drugs inhibit ovulation, the ovaries secrete less estrogen, the amount of estrogen contained in the drugs is also less, the endometrium cannot grow normally, the endometrium is thin, so the menstrual flow is reduced, or even menstruation stops. ② Breakthrough bleeding. If bleeding occurs while taking medication, it usually occurs after missing a dose. A small number of people may experience vaginal bleeding even if they have not missed a dose. ③Increase in menstrual flow and prolonged menstrual period.

The above is whether birth control pills affect menstruation. Long-term oral contraceptive use in daily life will cause some reactions of the body. The most common ones are the impact on the menstrual cycle, irregular vaginal bleeding, shortened menstrual cycle, too little menstrual flow, too much menstrual blood, as well as some common vaginal swelling and pain and some gynecological inflammation. Therefore, in daily life, it is better to take less birth control pills.
