Under normal circumstances a negative pregnancy test means that there is no pregnancy, except for the possibility of false negatives. Pregnancy is a very complicated physiological process, and many physical and chemical reactions will occur, and any problem in any of them will lead to the failure of this conception. A negative pregnancy test may also be a pregnancy: 1. False negative may occur due to the poor quality of the pregnancy test; 2. Due to the short period of menopause, the hormone level in the body is low and cannot be detected yet. This may affect the normal test results. It is recommended to use morning urine for the initial monitoring to avoid the influence of the drinking factor. Once pregnancy is confirmed, it is recommended to pay attention to rest, not to do heavy physical labor, pay attention to folic acid supplementation, prohibit sexual intercourse and regular pregnancy tests.
