The pregnancy test is not based on the time of intercourse, but on the time of cessation of menstruation. It is recommended that the patient choose to use a pregnancy test stick or pregnancy test paper to test the morning urine about 7 to 10 days after the menstrual period has stopped. If the test shows two red lines, it means a positive result, considering that the patient is already pregnant. If it shows two red lines, one dark and one light, with a weak positive result, considering that there is a possibility of pregnancy, and it needs to be rechecked in a few days to make a clear diagnosis. If it shows one red line and a negative result, it means that the patient is not pregnant. You can also choose to go to the hospital for a urine pregnancy test to clarify the diagnosis of pregnancy.
