Hi, Welcome to Health care magic forum.
H.pylori has nothing to do with the endocrines, and vice versa.
The lack of periods may be due to the
anemia,infection, or P.C.O.S,and other harmone disturbances.
I advise you to consult a gynecologist for diagnosis and treatment.
Take more of green leafy, vegetables, pulses, sprouts, and
protein rich foods,to assist the treatment.
Wishing for a quick and complete recovery.
