If your period is supposed to start this week, then you should be alright to take a test now.

i cant get a test thats the thing without my parents knowing i cant get one

Well sweetie, we can't tell you whether you're pregnant or not. Sorry, but we can't.

Try to relax and give your period time to come. If you used protection, the chances of you being pregnant are slim.

Why can't you get a test? Do you not have anyone that can drive you to the pharmacy? There isn't an age limit on purchacing those. If you can't do that, look up in your phonebook for planned parenthood. They will give you a test for free and give you a whole bunch of condoms so you don't have to worry about it in the future.
