Menstruation is a barometer of women’s health. Whether menstruation is early or late, women will be frightened, especially women of childbearing age. The delay in menstruation after intercourse makes them worried. It may be pregnancy, or it may be the onset of some disease.

Why does menstruation not come for a long time after having sex?

1. Pregnancy

If you have a high-risk sex life, you should be vigilant if your menstruation does not come on time. Especially if menstruation was regular before, but this time it is delayed for more than a week, you can buy a pregnancy test paper to test it. High-risk sexual life includes contraceptive use of extracorporeal ejaculation, contraception during safe period or lactation period, failure to take birth control pills in time, etc. Be especially wary of ectopic pregnancy, whose main symptoms are vaginal bleeding, cessation of menstruation and abdominal pain. When you suspect pregnancy, you need to go to the hospital for examination to determine whether it is an ectopic pregnancy through B-ultrasound and hcg.

2. Under the influence of drugs

Estrogen and progesterone determine the onset of menstruation. Abuse of hormone drugs can affect hormone levels in the body and lead to menstrual disorders. Common drugs include progesterone and short-acting contraceptive pills. Read the instructions carefully before each use to understand the indications and contraindications.

3. Influenced by life

Changes in living environment and emotions will affect the hormone secretion of the endocrine axis, causing menstruation to change. A common manifestation is delayed menstruation. The above factors can cause ovulation delays or disorders, making the menstrual cycle unable to be controlled by hormones, resulting in delayed menstruation. Normally, menstruation is very regular, but suddenly it is delayed. If pregnancy is excluded, the cause needs to be found, such as mood swings, significant changes in weight, high pressure in life, or irregular work and rest, etc.

4. Suffering from disease

Under normal circumstances, the menstrual cycle lasts from 21 to 35 days, which is normal. Occasionally, menstruation is delayed for more than a week at a time. After ruling out pregnancy, there is no need to be too nervous and anxious. You can observe it temporarily. If it occurs persistently, further medical diagnosis is required to find out the root cause. The main cause of delayed menstruation is ovulation disorder, because menstruation is the result of both estrogen and progesterone. Only estrogen stimulates the endometrium to grow but not shed. Post-ovulation luteinization and atrophy can cause changes in progesterone levels. Delayed ovulation or no ovulation will inevitably lead to delayed menstruation. If it happens once in a while, it may be due to changes in the environment or mood swings, but ovulation disorders often occur, and you need to be alert to polycystic ovary syndrome. The main symptoms of polycystic ovary syndrome are infrequent menstruation, body hairiness, acne and obesity. In addition, it is also possible that the ovarian function is declining, and you need to go to the hospital for six hormone tests to check the basic hormone levels.

Warm reminder

You should find out the reason for delayed menstruation after having sex, adjust your daily routine, get up on time, go to bed on time, take in balanced nutrition for the body, avoid excessive dieting to lose weight, strengthen physical exercise to enhance physical fitness, and reduce the frequency of staying up late. .
