<s>[INST] My 11 year-old daughter had an appendectomy 2 days ago. Today, she has a bloody vaginal discharge. She has not started her period, and I thought that she would be a late bloomer. I can t believe that this is her first period! Could it be related to the surgery? [/INST] Hi, I had gone through your question and understand your concerns.Bleeding from vagina do not occur after appendectomy, I mean it is not related to appendectomy operation . It may be her Ist menstrual period , if not other causes needs to ruled out. Hope this answers your question. If you have additional questions then please do not hesitate in writing to us.Take care.•     DISCLAIMER: - All the information provided here is for information purpose only   , it is not a substitute for the advice of a physician after physical examination , it is not intended to replace your relationship with your doctor.
