Hello I appreciate your query. A normal menstrual cycle is defined as having a length anywhere between 21 - 35 days, with individual variations, although the average most commonly found is 28 days. Also, the length of blood flow is generally 3 - 5 days, though the definition or normal varies between 2 - 8 days. Hence, going by normal definitions, your daughter is definitely normal. Also, 2 - 3 pads per day is not a heavy flow. However, you need to be careful as adolescent girls are most prone to anaemia, and since her cycles are short , as well as go on for longer period, she can develop iron deficiency. Make sure she consumes lots of green leafy vegetables, meat, liver, and protein rich foods like eggs, dal, paneer etc. Also, a girl s menstrual cycle takes upto a couple of years to regularize, that is the hormonal axis needs a couple of years after menarche to stabilize itself. Hence, she should have more normal bleeding within a year or two. If the bleeding during periods becomes excessive , painful or there is heavy passage of clots, you need to consult a doctor to rule out coagulation defects or any other problems. Hope this reassures you.
