Aunt means menstruation, and pregnancy can be detected by a delay in menstruation for about a week. The estrogen, progesterone and human chorionic gonadotropin in the body will rise after pregnancy and can be detected by a pregnancy test. The pregnancy test is generally accurate, but you must be sure to take it out after putting it in the urine for five seconds and leave it flat for five minutes before observing it. Women who have intercourse without contraception and have delayed menstruation are likely to be pregnant and can use early pregnancy test paper to detect this. Women can measure the value of HCG from blood about 14 days after conception. If the patient’s original menstrual cycle is around 28-30 days, she can test whether she is pregnant with ordinary test paper, such as urine test paper, urine pregnancy test, or more accurately, go to the hospital for blood test.
