Should I Be Concerned After Switched From Progyluton To Cyclacur For Menopause After Ovarian Surgery, And No Longer Having Periods?

I’ve been taking progyluton for years after ovarian surgery, for menopause. I’m 52, and recently moved to Greece where my doctor there prescribed Cyclacur for the same purpose. Whereas I always had a ‘period’ on progyluton, I don’t have it on Cyclacur. Is that a problem?
