I was Ovulating for 8 days straight once according to the LH tests. It was because my body was trying to and not succeeding.

You go by the first day you got your positive test.

I use that opk too and usually I get like 3 dark days and it's kind of hard to tell the day that I ovulated. So I just keep having sex till if starts to fade ..... Gotta love the cheapies ....
