I have an alarm set to take my pill at 11:am everyday. I recently went out of the country for about a week and continued to take my pill at 11, but forgot there was a time difference which was an hour behind. So I was technically taking the pill an hour later than usual. I am now on the fourth day of the placebo and still no period. It has also been about two weeks since I've had intercourse. Is it normal for my period to be late?
