If your period is normally regular and is delayed for more than a week, accompanied by nausea, vomiting, fatigue, loss of appetite and other symptoms, pregnancy is likely and you can use a pregnancy test. There are many kinds of pregnancy test sticks, but the methods of using them are not very different, and the steps are as follows: 1. use a disposable cup to receive an appropriate amount of urine; 2. check the validity of the pregnancy test stick, tear open the package and take out the stick; 3. put the test end into the urine and take it out after it has absorbed enough urine; 4. generally observe the result after 5 minutes, and if it shows two red bars, it is positive, indicating pregnancy. Note that because of the high concentration of hormones in the morning urine, the test is more accurate and it is generally recommended to use the morning urine for testing.
