Depends: Clots usually indicate excessive blood loss. If you had unprotected sex and a delayed period, it could be tissue from spontaneous loss of an early pregnancy. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.
