You need to calm down! You don't need to have a job to afford a test. Planned Parenthood gives them away for free, and even dollar stores carry them (I know you can find a spare dollar laying around!). In the absolute worst case scenario, head to an ER. They'll do a test and it'll be free.
There is absolutely no sense in getting yourself worked up if you don't know for a fact that you are pregnant. Personally, I'd think the odds are slim, but when you're sexually active you never know. Take a test!
I think it's great that you've made the decision to wait after this experience. A pregnancy scare is a terrifying thing and if you don't think you're capable of handling it right now, I'm so glad you're smart enough to just abstain.
Good luck to you.
