Ovulation test confusion!!

Melissa
Hi ladies, so I'm trying to find out once u use an ovulation test and get a positive result and find the day u are ovulating, do u continue to use that same time frame the next month and going forward? Or do u just keep having to buy ovulation tests every single month? Just curious, I haven't had a positive result yet but just asking so when I do. Any comments would be awesome!!! Thanks:)
