I'm going on vacation to the US and well, theres a time difference of 6 hours. Right now i take my pill at 10AM which would be 4AM EST (where i am going). I've been taking the pill one hour later each day trying to at least shoot it so i don't have to wake up TOO early.. Can i get pregnant by doing this?
The testing for the FDA certification showed that it is not that big a deal. If you look at the instructions an it says something like
"if you miss one active pill, take the missed pill as soon as you remember and take the next pill at your regular time, even if this means taking two pills at once. You do not need a backup method of contraception, as you will be adequately protected against pregnancy."
you are safe. Just do not make it a habit of taking pills irregularly.
Getting your cell phone to work here is normally a bigger issue than taking your pills at different times due to the time difference.
