Does contraceptive delay delay the effect?

Doctor contraceptive tome ... more every day delay a few minutes 10 a15 can I be at risk of becoming pregnant? And I also take the tablet without water because most of the time I'm on the bus and in places where I can not buy water. Can I use the tablet without water only?
Expert answer:

Delaying 10 or 15 minutes of the contraceptive's intake time will not interfere with its effectiveness (provided they are only 10 or 15 minutes). Taking the tablet without water also has no problem at all.
