Hii,
Welcome to HCM,
You are 24yrs and married. Delayed period for 2months and Pregnancy test is negative. You are suffering from OLIGOMENORRHOEA.
It has several reason like heavy weight, PCOD, hormonal imbalance,
thyroid disorder,emotional upset, abnormal eating habit ,some medication etc.
So need to investigate properly to rule out underlying pathology like USG lower abdomen, LH/FSH, Blood sugar,
Lipid profile, Thyroid profile,blood estrogen and
progesterone,
Prolactin level etc.
After all you consult your doctor regarding your investigation result and take proper medicine.
Take healthy diet,control body weight, take hematinics, avoid stress and sleep well.
All the best.
