If your period is delayed, you will first need to have a blood test to check your blood HCG level. If your blood HCG level rises, it suggests that your period is delayed due to pregnancy, and you will need to have a gynecological ultrasound further examined, and depending on the gynecological ultrasound, you will decide what to do next. If the blood HCG value does not increase, the delayed menstruation is due to menstrual disorder and further examination of the sex hormone test is needed. If the follicle stimulating hormone and luteinizing hormone in the sex hormone panel are within the normal range, you can consider progesterone withdrawal bleeding treatment, such as diflucan tablets, Imazin, Angiotensin, progesterone injection, etc. Normally, you will have a normal menstrual flow within two weeks after stopping the medication. If follicle stimulating hormone and luteinizing hormone of sex hormone six are rising, hormone replacement therapy can be considered if necessary according to the patient’s condition.
