I looked at the package insert for both my old
pill and new
pill, and they both said that when switching pills, to take the 21 active pills, and the 7 inactive placebos and then to resume the new pack on your normal date and time which is exactly what I did.
Since it does NOT say backup is required when switching if you follow that method, does that mean I am still fully protected and do not require backup?
I've been on BC for almost a year by the way.
