Plan b? can you tell?

Question

i had s*x thursday and it was my first time and at a time in the month where it would be hard to get pregnant, but i took plan b also. is there a way when you use plan b to tell if you might have been pregnant or do you never know?

Answer 1

Plan B prevents the egg from implanting so if you take it within 72 hours you don't become pregnant (of course we know it's not 100%) so no, there is no way of you knowing.
