Its absolutely possible to get pregnant just from missing one pill! It happened to me when I was just 19!
Its the day after the 14th, so I hope you're ready to take your test if your period comes! Just remember, either way, you're going to be ok!
It is possible, my friend and her husband now have a beautiful baby boy because she failed to take her pill at the exact same time every day. From my experience, I would say don't panic- you would not be able to tell that you are pregnant this early on- so you're probably just freaking yourself out. If you are pregnant, the baby would only be maybe the size of a pea or around that since it's only about two weeks and you wouldn't feel any movement or anything like that. Did you take two pills the next day like you're supposed to after missing a day? That's supposed to take care of any possibilities- read the information packet that comes attached to each pack of pills- that will tell you what to do when you miss a day and how many days you'd have to miss in order to have to use condoms or whatnot. Don't panic- hope this helps.
