Hello,
If the pregnancy tests have come out negaitive,then pregnancy is ruled out.But confirmation of the status of
pregnancy can only be done after serum HCG levels.Also this foul smelling white/yellow discharge can be due to
infections like trichomoniasis.I would suggest a gynecologist’s evaluation to confirm the diagnosis and to
find out the cause of amenorrhea in absence of pregnancy.This can be due to stress and anxiety, malnutrition,
depression, overexercising, sudden weight loss or gain (obesity),thyroid disorders or hormonal imbalance due
to polycystic ovarian syndrome(PCOS). Hope it helps.Take care and regards.
