Its possible. But a positive ovulation test shows a LH surge...meaning that you're ABOUT to ovulate, not that you are ovulating or have ovulated. So, the best way to use an ovulation test is to have sex the day of the positive test and the two after the positive test.
If you pair ovulation tests with charting your BBT, you can tell when you're about to ovulate (by the tests) and when you have ovulated (by the temperature rise).
