I took an ovulation test and it was positive. Then I took a different brand ovulation it was negative all on same day.......Did I ovulate?

Testing? Ovulation tests are a gimmic. Of course you ovulated. You do not need a test to tell you. If you are having your periods you are ovulating. Many women teach themselves to feel the ovation pain that comes when the ovary releases the egg. That pain is much more likely to be accurate than any gimmick known as 'an ovulation test.:'
