Delayed menstruation and no pregnancy test results

Many women will prepare for pregnancy for a period of time before giving birth to ensure the healthier growth of the fetus. Generally speaking, they will use test strips to test after the menstruation is delayed. However, some women find that the test strips do not show pregnancy even when the menstruation is delayed, and they don’t know what the reason is. In fact, delayed menstruation is very normal and does not necessarily mean pregnancy. It may be due to irregular menstruation. Pay attention to your diet and regularity, and get enough rest.

Delayed menstruation means that a woman's menstruation comes more than 7 days later than the normal menstrual cycle. A normal cycle for women is 28-30 days. It is still within the normal range if it is about 7 days earlier or later. The length of the cycle varies from person to person. If a woman finds that her period is more than a week late, it is considered a late period. There are many factors that affect menstruation, including emotions, medications, lifestyle, etc., and the specific factors vary from person to person.

Excluding pregnancy, delayed menstruation is mainly caused by irregular menstruation. There are many reasons for irregular menstruation, such as endocrine disorders, gynecological diseases, environmental changes, psychological factors, etc., which require treatment and regulation. If you have irregular menstruation, you need to find the cause first.

What causes delayed menstruation?

1. Pregnancy

After the menstruation is delayed for 10 days, you can go to the hospital for a urine pregnancy test. If the result is positive, you are very likely pregnant. There are also other symptoms of pregnancy, such as chills, dizziness, fatigue, nausea, vomiting, etc.

2. Medication

Taking progestin-containing drugs, such as progesterone, emergency contraceptive pills, etc., can prolong the luteal phase and cause delayed menstruation. Newer generation gastrokinetic drugs may also cause delayed menstruation.

3. Caused by surgery

For example, uterine surgery may cause adhesions in the uterine cavity or cervix, which may prevent menstrual blood from being discharged, thereby delaying menstruation.

4. Endocrine disorders

Obesity, excessive dieting, irregular living habits, premature ovarian failure, polycystic ovary syndrome, etc. can all cause endocrine disorders in women and lead to delayed menstruation.

5. Chronic diseases

Chronic hepatitis, tuberculosis, tumors, hypothyroidism, severe anemia, vitamin E deficiency, etc. often cause delayed menstruation.
