It is normal for your period to be delayed for two days, but you cannot rule out the possibility of an unwanted pregnancy. Generally, a delayed period is nothing but a menstrual disorder or pregnancy. There are many reasons for delayed menstruation, such as emotional or environmental changes, psychological stress, sex hormone problems, thyroid problems, etc. In Chinese medicine, it is said that kidney deficiency, blood stasis, blood deficiency and cold can lead to postponed menstruation, and women may have irregular menstruation at menarche or near menopause. These are normal phenomena. However, if you have sex, whether or not you have contraception, or whether or not you take the oral emergency contraceptive pill, or whether or not you are ovulating, you should be alert to the possibility of an unwanted pregnancy. You can wait a few days to test yourself with an early pregnancy test or go to the hospital to have your blood tested for human chorionic gonadotropin, because a urine test does not exclude the possibility of false negatives. In addition, if the period is only occasionally delayed, do not take special care of it, you can observe it for a few days, as long as you can have your period in the following week, it does not matter. In short, don’t be nervous if your period is delayed for two days, you can observe it for a few days, but if you have sex, pay attention to rule out the possibility of pregnancy.
