pregnant or not? when to test?

When should I test?? We have unprotected on the 19th and ever since last Wednesday I've been having symptoms (sore breasts, eating a lot more, moody, feeling like I'm gonna throw up, dizzy, tired, and feeling full but not from food) idk when to test. My period should come on the 9th. Can I test before? Does this sound like pregnancy? Help!
