If you usually have normal menstrual cycles and your period comes on time every month, and your period has been delayed for five or six days, you should first rule out whether you are pregnant or not, provided that you have had sexual intercourse. The easiest and most convenient way to detect pregnancy is to go to the drugstore to buy early pregnancy test paper, and then use the morning urine to test, if it is two bars show positive, it is confirmed to be pregnant. If you haven’t had sex and haven’t had your period after five or six days, you can wait a little longer. If you haven’t had your period in more than a week, you can go to the hospital for an ultrasound to check the thickness of the uterine lining. If the uterine lining is still relatively thin, you can take some medication or injections to promote menstruation, such as progesterone, and then you will have your period if there is retracted bleeding after you stop taking the medication. If the test is already positive, you can go for ultrasound examination to see if the pregnancy sac is in the uterine cavity, if it is outside the uterine cavity, it is ectopic pregnancy, ectopic pregnancy is to be hospitalized for timely treatment.
