First of all, you should undergo one blood test
for beta-HCG to confirm/ exclude pregnancy
at the earliest. Some times pregnancy test may be positive lately.
In exclusion of pregnancy, other reasons are hormonal
imbalance, stress/ anxiety, thyroid problem, weight gain/ extreme loss, irregular eating habits, psychological factor etc.
Need to investigate properly to pin point the diagnosis by complete hormone assay, thyroid profile, blood sugar & prolactin
level, vaginal swab test etc. Consult with your gynecologist for proper guidance and medication.
Avoid stress/ tension, take healthy diet with Vitamin & iron supplements
, control body wt, maintain genital hygiene and take sound sleep. Wear tight breast support to relieve discomfort.
Be well and take care.
