Thank you. My 14 year old granddaughter had her first period 1 1/2 years ago. She continued for a few months then it stopped until about 8 months ago, then stopped three months ago. She was diagnosed with precocious puberty about age 8. Never had hormonal therapy. Should I take her back to her pediatric endocrinologist? Is this serious. She is otherwise very healthy and active - runs cross-country.
