TTC year 2

Ok so we've been half heartedly trying for 2 years. If it happened great if it didn't that was ok too. Now we both agree it's time to get serious. Started taking chase tree and after AF (currently experiencing) we are going to be trying for real. So I want to start an ovulation test what is an inexpensive effective brand? What should I look for? I want to start now as to get a baseline.
