Testing question!

How many days past ovulation is ideal before taking a test? I'm curious because I have been super sick, had bowel troubles, super nauseous, had horrible indigestion for 2 weeks straight, been bloated, had cramps for 4-5 days straight, headaches, and pretty awful back pain. All of this is really not common for me. I am currently 4-5 days past ovulation. I know it's way too soon to test now, but when will be ok to?
