Thanks for trusting us about your health care.
I can understand your concern here.
The chances of pregnancy after taking plan-b after 46 hrs. is reduced to 42%%( means it
is 58% effective in preventing pregnancy).
So the chances of pregnancy are less in your case but plan-b should be taken as early as possible.
So do not take any stress and wait for your menses.
Hope it is useful, feel free to ask more questions.
