Morning After Pill

hey ladies! last night i had sex with my boyfriend and we had no condoms (also not on the pill or anything) and we aren't 100% if he pulled out in time, however I'm only 16 and in Melbourne you have to have a parent or guardian accompany you to buy the morning after pill if you're under 18, so my friend is going to get it for me, but, I also can't swallow tablets, so I was just wondering wether you can crush the tablet up and it will still have the same effect?
