Need some help

D • mother of 3 boys 💙💙💙 3 angel babies 👼 trying for a baby girl 💓💓

Gonna have a weird question I went to the doctor today and she wants me to start taking metformin along with the fertile cm pills, I already have the fertile aid for women are those the same or different?? Also with taking both of those can I still take geritol or should or switch back to prenatal pills?
