Early pregnancy test is performed by urine HCG, and it usually takes about 12 days after intercourse before the test can be performed. It takes about 12 days for the test to reach the mother’s bloodstream and then the urine after the sperm and egg have united, so it is important to choose morning urine or mid-urethral urine as much as possible to increase the accuracy of the test. A negative test paper means that you are indeed not pregnant and the results of the test are accurate. If it is two passes, you will still be pregnant at this time. If you choose to continue the pregnancy, you can go to the hospital around 42 days for an ultrasound to determine if it is an intrauterine or ectopic pregnancy, and just pay attention to all the tests during the pregnancy. If you choose to terminate the pregnancy, you should also go to the hospital at around 42 days to determine the intrauterine and ectopic pregnancy, and you can choose between medical abortion or abortion depending on the size of the pregnancy sac.
