Hello ma'am and welcome.
Varipus factors including trauma, stress
, surgery, etc; can influence the menstrual cycle and hormone levels. For this reason, I would first recommend a check on your hormone levels and a urine analysis before any doctor comments on the possible cause for your symptoms.
Although, in my opinion this is more of a hormonal
imbalance issue than any other, but it obviously requires laboratory confirmation.
Hope this helps.
