Testing 5 days before missed period?

I have to take clomid to achieve ovulation. After 4 yrs of sadness it took 2 months after starting clomid and i was pregnant!!!! ( i know it was supper lucky to conceive after just two months!) We arw trying for#2! Im 11days past ovulation and have lots of miner symptoms of possible pregnancy! So my question is would you test 5 days before missed period or would you wait?! I'm dying to know either way!
