Is it normal to miss your period for a week?

If a woman with regular menstruation misses her period within a week and resumes her period after a week, it is considered normal. If you don't have your period for a long time, you might be considering whether you are pregnant. If you are not pregnant, it may be due to drug factors or pathological factors such as the ovaries, uterus, and nervous system that cause the absence of menstruation. In addition, mentality, lifestyle, etc. may also affect menstruation. The actual reasons for missing menstruation are:

1. Pregnancy causes amenorrhea

If a woman has sex, she can use an early pregnancy test strip to test her urine 7 days after her period is delayed. If she is pregnant, the result will show positive; if she is not pregnant, the result will show negative. Of course, the best way to test pregnancy is to go to the hospital for a B-ultrasound examination.

2. Side effects of medications causing amenorrhea

Medicines can affect women's endocrine system. For example, taking emergency contraception, weight loss products, drainage methods and medicines can cause endocrine disorders in women, thereby affecting the menstrual period and causing amenorrhea.

(1) Emergency contraception: The main ingredients of emergency contraception are estrogen and female hormones. By taking emergency contraception, female ovulation is inhibited, thereby affecting the fusion of egg cells and male sperm, achieving the purpose of contraception. However, if you take too much emergency contraceptive, the ingredients in the drug will affect the secretion of estrogen by the uterus and ovaries, the uterine wall cannot grow normally, and the endometrium is thin, which will cause a decrease in menstrual flow or even amenorrhea.

(2) Weight loss products: For example, weight loss products containing hormone drugs generally contain thyroid hormones. Improper use of weight loss products can easily cause menstrual disorders in women, resulting in symptoms of irregular menstruation or amenorrhea, affecting normal menstruation. In more serious cases, it may cause infertility.

(3) Drugs for abortion: Medical abortion usually involves taking the protease-level anti-estrogen drugs mifepristone and misoprostol. These drugs will inhibit the dopamine receptors in the central nervous system, reducing the amount of factors released by the hypothalamus and pituitary entering the anterior pituitary gland, thereby causing a decrease in gonadotropin and corticosteroids secreted by the anterior pituitary gland, resulting in amenorrhea and delayed ovulation. After the drainage method drugs enter the body, they will damage the uterine wall, which requires a period of repair. Generally, the menstrual period will resume in about a month after medical abortion, or the menstruation may not come for 40-50 days.

3. Surgical treatment causes amenorrhea

The postoperative period will be affected. For example, intrauterine surgery may cause cervical adhesions, resulting in menstrual blood stasis in the uterus, resulting in amenorrhea and delayed menstruation.

(1) Artificial abortion: Artificial abortion generally includes vacuum aspiration and curettage. If the curettage is not performed properly, it is easy to cause damage to the cervix or damage the basement membrane of the uterine wall, resulting in adhesion of the internal os of the cervix or adhesion of part of the endometrium, thus causing amenorrhea.

(2) Surgical treatment of ovarian cysts: After surgery for ovarian cysts, the uterus and ovaries need some time to repair. Some women resume their menstrual period one month after surgery.
