Is it safe to take benadryl after taking Plan B?

I took Plan B a little more than a week ago and I was wondering if I took benadryl if it'd mess up the pill??

    The Plan B has been out of your system for several days now. The Benadryl wouldn't have affected it anyway.

    It won't affect Plan B, especially a week after you took it.
