<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, i used nuvaring for 3 months and for the fourth month i decided that i wantedto stop having periods. I inserted a new ring immediately after taking the old one out. I have been bleeding for three weeks. The first two weeks were spotting but now im having very heavy bleeding. Is this normal and how long will it last?  <response>: Hi, The current bleeding is due to the breakthrough effect of the hormone. As you did not have the with Chat Doctor. I would suggest a check-up by your consultant and take styptics and hormone supplements for arrest of the bleeding. You will also need mineral and vitamin supplements to make up for the blood loss. Maintain a healthy body weight as this can help in maintaining proper hormonal balance in the body. Hope you find this information useful. Take care.
