TOOK THE MORNING AFTER PILL.......?

I took the morning after pill this morning but i lied about my age to the guy at the chemist. i said i was 16 and give him a false date of birth. he wrote down my adress and details and so fourth. is there any way hel find out i lied about my date of birth and then contact my parents? that would be the worse thing that could hapen.im sure a alot of girls under 16 have lied about their age to get the pill without having to contact their parents. personal experience would be great...
