Hi Gretings from health care magic
Scanty flow during menstrua; cycle is called hypomenorrhoea. it has so many etiological factors . among them emotional factors like stress
, tension, worriedness, hormonal
problems like hypothyroidism( u check your TSH level
. if it is comes higher than 5 then you have hypothyroidism), lack of exercise, crash dieting, change in the environment like change in job, if you have a small uterus
so to rulled out any medico related cause do a USG of lower abdomen and Blood test
for TSH. if both are normal then modify your life style looking to the cause mentioned above. but it will not cause any problem in your future maried life. thank you. hope it will help you.
