Medicine for pcos

any lady’s taking spironolactone for their pcos & ttc? If so what were some side effects? Did it help? Did it make your period wonky? I usually have regular periods & ovulate every month (but later in my cycle) but this cycle I’m 15 days late. I started taking it & I was apx 8 days late anyways, I don’t if I should write it off at the medicine making me late or what!
