Q: My 13 years old daughter hasn't started her menses yet. She had a blood clot twice and we thought it may be the beginning of her menses, but nothing happened after that. Is this a matter of concern? Is this a normal condition or should I discuss this with a doctor?

A:In some people, once the period has appeared as a spotting, as it has in your daughter's case, there maybe a gap of some months, or even a year till the menses become regular. This is because the ovaries may not be producing the eggs regularly. If you are very worried, you can get an ultrasound done.
