My period is 100% blood clots. i usually have clots, but not like this. there is no liquid blood at all, just clots. should i be worried?

Yes: It is time to see your local GYN MD as heavy clotting is very abnormal and can run the risk of serious anemia over time as this is arterial not venous menstrual bleeding.

Agree with Dr. I: You should start taking oral iron and multivitamin supplements to prevent anemia. Have a healthy diet, exercise, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine Nutrition: http://www.choosemyplate.gov/.
