Do I start my new birth control in the middle of my old birth control?

I was prescribed a new birth control (Ortho Tri-Cyclen Lo) today but I'm still in the middle of my old birth control pack (Yaz). I want to know if I finish my old pack first before I start my new one or start my new one right away?Do I start my new birth control in the middle of my old birth control?
Definitely finish out your pack before starting the new one. They are made with different hormones, and that's something you don't want to mess up.Do I start my new birth control in the middle of my old birth control?
Yes, you finish the old pack first.





Look in the booklet contained in the new pack, there will be a section that gives guidelines ';when switching from another brand Birth Control Pill';
