Hello,
Thank you for your query.
Menarche, the start of menstrual cycles, can be a irregular. This can be so for the first few years.
Some heavy bleeding/prolonged bleeding is expected as well. However, heavy AND prolonged combined may be too stressful for your daughter.
This issue needs to be addressed.
I recommend you see an
Pediatrician or a gynecologist to rule out any
hormonal imbalances or other problems (like
Endometriosis) as a cause for the excessive & prolonged bleed.
Don't worry if it is irregular or if there is prolonged scanty flow after the first 3days.
This should normalize by the age of 14-15. If not, or if there is heavy bleeding even after the 4th day, consult a gynecologist.
If she does need hormonal therapy, I recommend trying alternative medications like
Homeopathy first. This will help regulate cycles and reduce bleeding without the side effects. If this too doesn't help, she may need hormonal therapy for a couple of months.
Hope I've answered your questions.
Please let me know if there is anything else I can help you with.
Wish you both good health.
