Do I ovulate?

Amanda
Hi I would like to know if the strips showing a light stripe mean that I will ovulate sooner or later.
I haven't been tested at the doctors to see if I ovulate every month and would like to know if I actually do ovulate, because I only started getting regular on time periods 6 months ago after I lost 30kg. 
I did a strip just now and it is about half the way there so does that mean I am on the way to ovulating and that I definitely will ovulate because it's there?
