What does a negative pregnancy test mean?

As people's minds continue to open up, many people's concepts are also changing, so pregnancy test sticks have become something that many people are familiar with. However, many people are still not very clear about the negative and positive results of pregnancy test sticks. Therefore, when some women feel unwell, they use pregnancy test sticks to find out whether they are pregnant, but they are not very clear. So when a female friend uses a pregnancy test stick and the pregnancy test stick is negative, what does it mean?

A pregnancy test stick is a pregnancy test product that uses the reaction between single and multiple HCG antibodies in the device and antigens in the urine to determine whether a woman is pregnant. It can detect whether a woman is pregnant from the urine about 14 days after sexual intercourse. It is an upgraded product of early pregnancy test paper.

Negative: A purple-red line appears in the test area (control line C), indicating no pregnancy.

The accuracy rate of pregnancy test sticks from regular brands is about 85% to 95%. First of all, we need to clarify some issues. Ovulation occurs around the 14th day of the menstrual cycle. Assuming 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.

Through the above introduction, we understand the reason why female friends use pregnancy test sticks, and what does a negative pregnancy test stick mean? That is, the woman is not pregnant. We all know that the accuracy of pregnancy test sticks is very high. If you still have objections to such results, you can choose to go to a regular hospital for examination, so that the results will be more accurate.
