Thanks for writing to us with your health concern.
Maybe this is just your normal menstrual pattern now.
If the spotting and discharge have been constantly 4 days after your period every month, it is a regular pattern.
It would have been worrisome if the spotting and discharge varied through the cycle, or you had pain and cramps alongwith.
That might have pointed towards endometrial hyperplasia
, or a fibroid or cyst.
Sometimes, stress, late nights, erratic eating, weight gain, smoking, drinking, drugs, radiation
, ingestion of hormonal
medications, travelling , anxiety - all can cause spotting.
It is wise to plan a Pap smear
, however, also ensure that you get a pelvic transvaginal scan, a thorough internal evaluation ( per vaginum and per speculum ) and thyroid levels checked also.
THat would be a comprehensive workup.
All the best.
Please feel free to discuss further.
