yes, of course, even when taken correctly they are not 100 percent, and if they are not taken correctly, they are not effective.

Did you mean to say she is "now" 1 month late? If so, and she is normally quite regular with her periods, it certainly could be due to being pregnant. Being unusually tired happens to many women in the early stages as well.
She really does need to take a test though to be sure and should see her doctor if she thinks it is likely. Hopefully congrats will be in order for both a much wanted pregnancy and an upcoming wedding.....
