Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
At the time you was about to get period, you had a pink discharge, lasted for 4 days. lowered immune system, rare cramps, thick white discharge,
nausea after each meal, bloated, off the pills since 1 year, hot flushes, feel like
fever, test showed nothing. your doubt is whether you are pregnant.
The pink discharge can be considered as the period. Causes could be white discharge, infection,immunodefeciency, can cause fever, hot flushes, etc. other causes could be
anaemia,
anxiety etc.
I advise you to consult a gynic for diagnosis and treatment.
Wishing for a comfertable recovery.
Best regards.
