im set to always take my pill at 11:30pm...is it ok if i take it like 1/2hr before or after some days? sometimes its hard for me to be exactly 11:30. will this cause a problem in the pill protecting me?
Yes you can, just try to keep it as close to the same time each day as you can. Try not to let it go over an hour tho, not because it'll stop working but just to maintain a good routine.
A small variance is ok. One reason why it is better to always take it at the same time is that you won't forget, it will become part of your daily routine.
