Contraceptive pills

Hi, I have a question lang po regarding sa pills. I am using Daphne Pills po, and I am planning to try other brands like lady or trust pills since hindi na nag b.breastfeed ang baby ko, 1yr and 2months na po sya ngayon and pure formula milk na po sya. Okay lang po ba to change it?? And dapat po ba maubos ko muna yung pakete ng daphne pills ko bago mag try ng ibang brands?? Salamat po in advance. #1stimemom #pleasehelp #advicepls #firstbaby
