Ovulation Test Strips - Worth it or not?

Sammi

I brought some basic ovulation test strips last week as I'm never really sure when I ovulate. I spoke to my doctor about them and they told me not to bother with them.

Have any of you ever used them to help? Were they worth it?

The pack I had was only a pack of 5, and even though Glow tells me I'm in my fertile window, all the ovulation tests came back negative.
