Pregnancy test paper strong positive turned weak positive

Generally speaking, women can get accurate results by using early pregnancy test strips one week after their menstruation is delayed, and whether the test result is strong positive or weak positive one week after the menstruation is delayed, it means that the pregnancy is 6 weeks. But some girls ovulate early, and get a strong positive result when they take the test just after their menstrual period. However, the test paper slowly turns into a weak positive result when they are 6 weeks pregnant, which makes them very worried. So, what causes this situation?

1. After pregnancy, the early pregnancy test paper mainly detects human chorionic gonadotropin in urine, also called hCG. Generally speaking, the 6th week of pregnancy is the stage of large-scale metabolism of human chorionic gonadotropin, and under normal circumstances, the human chorionic gonadotropin standard value will double the next day. However, if the test paper turns from strong positive to weak positive at 6 weeks of pregnancy, the first thing to be alert to is that the fetal sac is not developing well. It is concluded in clinical medicine that abnormal development of the fetal sac will affect the secretion of human chorionic gonadotropin, thereby causing a decrease in the content in the urine, and the test paper will turn from a strong positive to a weak positive during the test. The main reasons for poor gestational sac development are problems with the gestational sac itself and insufficient progesterone levels that cannot support the growth of the gestational sac. When female friends encounter such situations, if they do an ultrasound examination and find that the gestational sac is abnormal, they should promptly take treatment measures under the guidance of a doctor.

2. In addition to the fact that the secretion of human chorionic gonadotropin decreases, which will cause the test paper to change from a strong positive to a weak positive at 6 weeks of pregnancy, if its secretion is extremely high, it will also cause the test paper to change from a strong positive to a weak positive at 6 weeks of pregnancy. For example, some women are pregnant with twins or multiple babies, or even have a hydatidiform mole. The concentration of human chorionic gonadotropin in the urine is too high, which will also affect the sensitivity of the test paper.

It should be noted that when testing, you must choose the latest production of early pregnancy test paper, do not use expired or damp test paper, and use it strictly according to the instructions to ensure the accuracy of the test results. Secondly, after pregnancy, you must do relevant check-ups regularly, especially if the test paper shows a strong positive and the pregnancy period is already 40 days and above, you should go to the hospital for B-ultrasound examination in time to confirm whether the pregnancy is normal in the uterus.
