Generally, a woman who does not have her period for 57 days can detect pregnancy with a pregnancy test, but there are individual differences.
Women who have regular menstrual cycles and are sexually active should be highly suspicious of pregnancy when their menstrual cycle is delayed for more than 10 days. After the menstrual period has been delayed for 10 days, you can use early pregnancy test strips to detect HCG (human chorionic gonadotropin) levels in morning urine to make a preliminary judgment on whether you are pregnant or not. So in general, when there is no menstrual period for 57 days, it is possible to detect whether you are pregnant or not by using test strips.
Pregnant women in early pregnancy should pay attention to rest, not too tired, do not do strenuous exercise, prohibit coitus, pregnant women should also continue to follow the doctor’s advice to take folic acid on time. At about 40 days of pregnancy, you can go to the hospital to do ultrasound to determine whether the fetus is a normal intrauterine pregnancy, and after that you should also be regular obstetric examination.
There are many reasons for not having a period for 57 days, not necessarily due to pregnancy. It is recommended to go to the hospital promptly after this situation occurs and under the guidance of the doctor to conduct the appropriate tests to clarify the cause.
