Early pregnancy test, if it is weakly positive means there is a possibility of pregnancy. In addition, there are a few drugs that may affect the result of the early pregnancy test, such as birth control pills. If the early pregnancy test is weakly positive, you need to go to the hospital for further examination, mainly to draw blood for chorionic gonadotropin, which is the most accurate hormone in the blood and the most accurate and true reflection of the hormone level in the body. If the chorionic gonadotropin in the blood exceeds the normal range, it means that the probability of pregnancy is very high, and it needs to be combined with the ultrasound results for a comprehensive analysis.
