Is it possible that pregnancy cannot be detected?

When there are some symptoms of pregnancy, pregnant women should go to the hospital for examination in time, or check with a pregnancy test stick at home. The accuracy of using a pregnancy test stick can be said to be relatively high, but it is also possible that no result can be detected. Going to the hospital for a blood test is relatively accurate. If you find that you are pregnant, you should pay attention to conditioning and strengthen the conditioning during pregnancy.

Is it possible that pregnancy cannot be detected?

There are mainly two situations: one is that the time is too early and the changes in biochemical indicators are too small to be detected; the other is early biochemical pregnancy.

For women with regular menstruation, if amenorrhea occurs, the pregnancy can basically be determined by testing urine HCG or blood HCG. However, for women with irregular menstruation, since the menstrual period is not fixed, the ovulation time is also not fixed. If ovulation is delayed, although menstruation has been postponed in terms of time, the ovulation time is still relatively short, so the fertilization time is also relatively short. HCG can only be secreted in the female body after the fertilized egg implants. The fertilized egg usually begins to implant 6 days after fertilization, so the fastest time to detect it is 7 days. However, fertilization may not occur immediately after ovulation, and the HCG value is relatively low when implantation just begins, so it may not be detectable. Therefore, we generally recommend testing about 14 days after intercourse, which will be relatively more accurate. Therefore, if the test is performed too early, pregnancy may not be detected.

There is also a special situation called biochemical pregnancy, which means miscarriage just after becoming pregnant. Early miscarriage at this time may only manifest as delayed menstruation or excessive menstruation, with no obvious symptoms. If HCG monitoring is performed, it will be found that HCG will only rise slightly and then return to normal, so it is also called hidden miscarriage and is not easy to detect. If you do not test when HCG is elevated but only test when it is low, pregnancy may not be detected. But in reality this situation falls into the category of miscarriage.

How to detect pregnancy

Go to the pharmacy to buy an early pregnancy test strip. It is best to use morning urine as the specimen for testing. Once the result shows "squad leader", there is more than 80% chance that you are pregnant. You can go to the hospital to draw blood and urine for HCG testing. Especially if HCG can be detected in the urine, it can basically be confirmed that conception is successful.

It is indeed very worrying to encounter all the signs of pregnancy but not be able to detect the pregnancy. The above shows that this may be because it is too early or an early biochemical pregnancy has occurred. Therefore, when you encounter this situation, don’t be too anxious, maintain an optimistic and happy mood, go to the hospital for examination in time, and remember to test whether you are pregnant scientifically and take care of your body.
