Is it normal to not be able to detect pregnancy after one month?

For those who are eager to become parents, pregnancy is a problem they are more concerned about. However, some people are anxious to prepare for pregnancy, so after their menstruation is delayed for 2-3 days, they start to worry and think whether they are pregnant. We can understand everyone's mood. So is it normal if the pregnancy cannot be detected after one month? Let’s analyze it in detail below.

1. The time of testing. HCG usually appears in the urine a few days after the fertilized egg implants, and it must reach a certain amount to be detected. Therefore, for women with normal menstruation, HCG can only be detected in the urine after the menstruation is delayed. Women with long menstrual cycles or abnormal ovulation can only be detected after 40-44 days of amenorrhea.

2. Dilution of urine. Drinking too much water can dilute your urine and cause a false-negative result.

3. Performing the test in the morning or evening may have a certain impact on the results. The highest HCG value is generally found in morning urine, so many instructions recommend testing in the morning, but this is not absolute.

4. When testing, pay attention to the length of the test paper immersed in urine. Sometimes the length of urine that covers the test strip is too long, making the test result difficult to interpret.

5. Do not use the test results to determine whether you are pregnant if you have had a recent pregnancy. Because HCG can remain positive for a long period of time after termination of pregnancy (after delivery, spontaneous abortion and artificial abortion).

6. Some diseases and drugs may cause false positive results. Some tumor cells, such as hydatidiform mole, choriocarcinoma, bronchial carcinoma and renal cancer, can also secrete HCG.

There are many factors that affect the test results in early pregnancy. For example, if the test is done too early, the HCG content in the urine is relatively low, and it may not be detected at this time. Another reason why the test cannot be detected one month into the pregnancy is that the results will be different between testing in the morning and evening. I hope that people who are preparing for pregnancy will not be anxious and be patient and wait.
