Since you are giving a range for ovulation, I'm guessing you're just tracking your period dates rather than charting BBT and CM. That means you may ovulate during that time, or may not, but you don't actually know. I'd recommend charting to learn exactly what your body is doing.
Just take a test. If it's a BFN, then you're not pregnant or it's too early. Keep testing 1x a week until your period, BFP, or CD60. If you hit CD60, call your doctor.
All of this in the newbie link, including a chart of when to test according to DPO.
