Hi, I have abnormal menstrual cycke since a year. I tried to lose weight and I did exercises as well but somehow its not happening although I am not out of range BMI. Its late sometimes month or sometimes days. I also feel weakness a lot. I work so I need energy. I want some multivitamins to be prescribed for skin hair eyesight and immunity. I also have started facing severe migraines
