Perimenopause Hot flushes and abilify

Hi I am 47 years old female diagnosed with chronic schziophrenia and taking 10mg in morning of abilify. Only been taking for 2 weeks as previous meds of modecate not been made by pharmaceautical company anymore. No periods for 3 months hot flushes and sweating happening for 3 months until today when I missed abilify dose. Perimenopause? Medication? Having Fsh level and other tests. Any other women going thru similar issues?
