Your gonna have to wait until your next period to test. Symptoms also don't happen that quick so more than likely your sick because your stressed about whether or not you pregnant.

Doubtful that pregnancy symptoms are manifesting that quickly. Probably stress, or just a badly timed flu! Try to relax (practically impossible , I know, but important) and wait for your period. Keep in mind that stress can also delay your period, so if you are more than a week late get and take a test but not before. You'll just waste money.
