opk?

i can't believe i forgot the basics but i have an opk question.

since i got my 1st pp af this month after 9+ months i started using the cheapy opk's to see if i'm ovulating at all. there was a slight line yesterday (not nearly as dark as the control line but if it were a pg test it would be +.) anyway today i have nothing at all. does that mean it may have been + yesterday and i just missed the surge or maybe i'm not really "o"ing yet (can be a million reasons for that) ?

Re: opk?

With OPK' the line color has to be the same or darker. I think it has something to do with the LH hormone being present throughout the month. I'm guessing that you probably have not ovulated yet.
