After passing tissue and bleeding i took a hpt, which was postive. the next day my blood hcg was 6. is this an early miscarriage?

May be: About 25% of early pregnancies are lost spontaneously, mostly due to chromosomal defects in the embryo. You may have experienced loss of an early pregnancy. Wish you good health. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.

Very likely.: This was very likely an early miscarriage. Unfortunately about 20% or so of pregnancies result in a pregnancy loss. Generally this should not increase your risk of future pregnancy loss. Hope this helps.
