Hi, Welcome to Health care magic forum.
Once you make the taking pills irregular, there will be possibility of the irregularities in the periods.
The other possibilities may be the anemia
, infection etc.
I advise you to consult a gynecologist for diagnosis and treatment.
I usually prescribe to my patient with such symptoms fluconazole
Take more of green leafy vegetables,pulses,sprouts, and protein rich foods to have good health and resistance. Wishing for a quick and complete recovery. Thank you.
