Hi welcome to Health care magic forum.
Thanks for writing to H.C.M.F.
As you narrate, you are suffering with stomach cramps
, general fatigue
, foul smelling discharge , bleeding 8 days after your last period, with lower abdominal pain
and back ache,feverish and chills
. You are thinking it is the effect of the weather.
It appears to be the urinary tract infection
, or oelvic infection. I adviseyou to consult a gynacologist for diagnosis and treatment. The infection may cause the bleeding some times.
Wishing for a quick recovery.
