Changing start date: does it change the effectiveness of birth control pill?

I've been using birth control pill (Ortho Tri Cyclen Lo to be exact) for at least 6 months now. My start date is always Sunday, around 9pm. Last month I forgot to start the new pack on a Sunday, so I took my first pill the very next day, Monday, around 9pm. Effectively, I have changed the start date of the pack (delay it by 1 day). Will this change the effectiveness of the pill?Changing start date: does it change the effectiveness of birth control pill?
So long as you don't have unprotected sex straight away. make sure you are careful for the first couple or weeks to a month
