If the discharge is of a stretchy clearish consistancy then you have probably not ovulated yet..But are very close to it.
I would continue taking that test for the next 2 or 3 days, if this is the case.
There is a great book you might want to read. It's called taking charge of your fertility and it teaches/shows you your body's fertility signs. Great, great book!
Positive thoughts headed your way!
