The best time to test for early pregnancy is related to the testing method. Generally, the blood HCG test can be performed about 8-10 days after sex, and the pregnancy test can be used about 14 days after sex. Usually, since the blood HCG rises earliest after pregnancy, the blood HCG test is earlier than the pregnancy test paper, usually 8-10 days after intercourse. If you use a pregnancy test, you need to use the morning urine after waking up because the urine is more concentrated at this time, so the test result is the most accurate and less likely to be a false negative. If you want to determine if the pregnancy is intrauterine, you need to test by ultrasound. The best time to do this is usually around 5-6 weeks of pregnancy to determine if there is a double ring sign and a gestational sac. If pregnancy is confirmed, you should pay attention to a light diet during early pregnancy, eat more fresh vegetables and fruits, avoid greasy and spicy stimulating foods, and be properly active to strengthen your body’s immunity.
