Hi, Thanks for posting in HCM. I understand your concern. NuvaRing is a flexible plastic contraceptive ring that releases a low dose of a progestin and estrogen over three weeks. NuvaRing regimen specifies insertion of the ring into the vagina for a three-week period, then removal of the ring for one week, during which the user will experience a menstrual period. What bleeding you have experienced is called unplanned bleeding , which could range from spotting to heavy flow, when you start using the ring for the first time. Unplanned bleeding occurs most often during the first few months of NuvaRing use. Such bleeding may be temporary and usually does not indicate any serious problems. Hence, it is important to continue using the ring on schedule. If the unplanned bleeding or spotting is heavy or lasts for more than a few days, you need to seek medical attention promptly. Hope the information provided would be helpful. All the best.
