Is a endometrial stripe measuring 0.4 cm okay or not good?

The importance of endometrial stripe thickness depends on pre or post menopausal uterus, the timing the US is done during the cycle and the indication of the pelvic ultrasound. So if you have the US done due to abnormal vaginal bleeding, this thickness rules out endometrial hyperplasia as the cause but if you want to get pregnancy then this result is not good if US was not done during period time.
