Ovulation tests as pregnancy tests?

I’ve heard so many stories about people saying they had positive O tests with their positive pregnancy tests.

I had a faint line on a pregnancy test but only a faint line on the ovulation test. They said ovulation tests can’t tell the difference between lh and hcg so they will always be blazing positive.

That can’t be always right?? Especially since I was supposed to start af today and I didn’t. I’ll be calling my dr on Monday if af still hasn’t come but I definitely think I’m pregnant.

And my cheapie $1 ov test.
