hi, thanks for using healthcare magic
It is possible that stress is contributing to your light periods.
Decreased or irregular menstrual flow may be caused by : emotional stress, physical stress such as illness, inadequate diet, high prolactin
levels, abnormal thyroid
hormone levels and polycystic ovarian syndrome
.The use of oral contraceptives can also cause a lighter period.
Though emotional stress is the likely cause, you may want to consider visiting your doctor for an evaluation. He or she examine you and conduct any necessary investigations such as blood test
for certain hormones and possibly an imaging procedure such as an ultrasound
I hope this helps
