Ovulation test as early hpt?

sierra • Mother of a 8 year old(rainbow), and a 2 year old (rainbow), and an angel baby girl❤ (lost my pot of gold), trying for another 🌈 .
So impatient as I'm only 6dpo but I heard you can take ovulation tests as hpt also? I noticed my lh line is way darker than the control line, thoughts? I have one pregnancy test I just want to save it but...so impatient. : )
