Clear Veins in Period Tissue: What to Know

During your period, it is common to pass tissue or material from the lining of the uterus.

The clear veins you observed in the tissue are most likely small blood vessels.

As the uterine lining sheds, it can sometimes include small bits of tissue that contain blood vessels, which is perfectly normal.

These veins can appear clearer during your period due to the higher levels of estrogen and progesterone in your body, which can cause the blood vessels to become more visible.
