Are pregnancy tests accurate during lactation?

It is best not to get pregnant during breastfeeding. You should take protective measures at this time because your body is still in a state of recuperation. If you get pregnant, it will cause secondary damage. However, if you use a pregnancy test stick to detect that you are pregnant, you must go to the hospital for further examination. In this way, you can make some more accurate judgments and avoid misdiagnosis.

First of all, we need to clarify some issues: ovulation occurs around the 14th day of the menstrual cycle. Assuming that fertilization is successful at this time, it will take at least 6 or 7 days for the fertilized egg to produce HCG. Pregnancy test sticks are determined by testing urine HCG. HCG actually starts to be secreted in large quantities after the fertilized egg implants, and the syncytial trophoblast begins to secrete large amounts of HCG. It takes at least 11 days for the fertilized egg to implant.

So, the earliest is 6 days. If you want more accuracy, wait until 11 days, as it will be more accurate then. You can make your own guess.

The pregnancy (positive) result can be read after 1 minute (30 seconds at the fastest), which means that if two lines are clearly shown after 1 minute of testing, it indicates a pregnancy (positive) result and there is no need to wait for 3 minutes before reading.

The result of not being pregnant must be confirmed after 3 minutes. This is because in the early stages of pregnancy, the HCG hormone content in the urine is very low, and a weakly positive result may appear during the test. The weakly positive result may not be displayed after 1 minute. As the reaction time increases, it will take 3 minutes for two lines to appear. At this time, the appearance of two lines should still be interpreted as a pregnancy (positive) result. If there is still only one control line after 3 minutes, it can be judged as a not being pregnant (negative) result.

The results judged after 5 minutes are invalid! This is because the results judged within 5 minutes are used as the experimental basis for designing products. The results judged after more than 5 minutes or even longer are not clear. Some people may have false positive results, and this result does not represent the actual situation.

1. Try to use the first urine in the morning for testing, because the hormone level at this time is easiest to detect. If this is not possible, make sure the urine is in the bladder for at least four hours before testing.
