How would you know you've had a miscarriage if you suspect you were only about 3 weeks pregnant?
So many times the zygote has defective chromosomes. It is possible that you get pregnancy almost every month after the marriage and the defective zygote goes out with your menses only. The normal or near normal pregnancy is preserved by nature. So you may not notice miscarriage of only about three weeks. It is not necessary to know the same. That is expensive and useless.
