There are three main methods for patients to test for pregnancy on their own: first, using a urine pregnancy test, which is the most direct and accurate method. If the patient has had intercourse for about half a month after the last time, the patient can use the urine pregnancy test to accurately determine whether or not she is pregnant, and it is generally recommended that the patient use morning urine for the test. Secondly, the patient can determine whether conception has occurred according to the change in basal body temperature, which normally rises by 0.3-0.5℃ after ovulation. If this high phase of body temperature can be maintained for 16 days, it indicates the possibility of pregnancy, and if it can be maintained for 20 days, it means that the patient is conceived, but only on the basis of a more accurate examination of the patient. Thirdly, it is mainly based on the clinical symptoms of the patient. If the patient has intercourse, there is a possibility of pregnancy, and the patient is now experiencing early pregnancy reactions such as delayed menstruation, breast swelling, nausea and vomiting, it indicates the chance of pregnancy. However, this kind of accuracy by observing symptoms is not high, and further judgment by checking urine or blood or ultrasound is needed.
