Hi, Welcome to Health care magic forum.
Of course, at any moment you can go for other tests for excluding the pregnancy
. Other than the pregancy, the other causes are pelvic infection
, UTI, stone in the urinary tract
, or colitis
To exclude the pregancy you can get the H.C.G. test, or the trans vaginal ultrasound
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to hasten the recovery.
Wishing for a quick and complete recovery. Thank you.
