The pregnancy test is usually most accurate in the morning when the morning urine is used for testing, because the HCG value in the morning urine is relatively high. At this time, choosing a pregnancy test can effectively improve the accuracy of the test and make it clearer whether you are pregnant or not. However, there are many brands of pregnancy tests available in the market, and the results of pregnancy testing with a pregnancy test are subject to chance. It is recommended that if a woman’s next period does not come on time and is delayed for more than a week, she can take a preliminary pregnancy test under normal intercourse. Even if there is a bar on the pregnancy test, do not blindly conclude that you are not pregnant, you can take the test again the next day to determine more accurately whether there is a possibility of pregnancy.
