I wouldn't get too worried yet, its not
been long. If it was just on the 18th,
give it a month, you will have to sweat it
till then

but just incase
you didn't know (this is for anyone) there
is a new drug out that you can take within
72 hrs (or something like that) after you
have had unprotected sex, and it will
prevent pregnancy. That doesn't mean go
out and have all the unprotected sex ya
want, cuz there are still many other
things much worse than a baby out there !!

but anyway, good
luck to you. Let me know what happens..
Ok ? But I would for sure give it atleast
3 weeks. Ok ... Take care
