Can I take any pills from my pack?

Can I take any pills from my contraceptive packet or do I have to follow the days of the week? For example, can I take one of domigo and tomorrow the one of Tuesday?
Expert answer:

It depends on the contraceptive, if it is 21 tablets and all the same color, there are no problems, if it is 24 or 28 tablets with different colors can not change the tablets do not.
