Thanks for the query.
Scanty flow during periods is called hypomenorrhea
This can occur due to many causes like :
imbalance as in poly cystic ovary disease, stress and strain, weight changes etc
- Anemia etc.
- If there is any possibility of pregnancy
, better to rule out ectopic pregnancy or miscarriage
If there is no possibility of pregnancy, you can watch in the next cycle.
Possibly by improving the nutrition the flow may improve in the next cycles.
If there is possibility of pregnancy, once consult gynecologist, get examined and go for ultrasound
By this workup the possible cause for your problem can be identified and treated.
