Where do I find ovulation tests?

Marie • #2 due June 16th 2017 <3

So I'm new to the whole actually trying to get pregnant scene. It's been a few months with no success so I thought I'd buy some ovulation tests to get more information. But then I realized I've only heard of them on this app!

So are they just at Wal-Mart in the family planning section and I just didn't notice them among the pregnancy tests? Or are they sold in different stores/sections?

Thanks!
