Ovulation test for pregnancy?

Erin

Has anyone used ovulation tests as an early indicator for pregnancy? I took one when I tested at 6DPO and it was stark white negative and then I took one today with a random urine (not first morning) and it was a lot darker - I know I'm only 7DPO but I was just curious if anyone has tried this and had any luck with it?

Or if they did and it worked, what there results looked like 7/8 dpo ish!!

Thanks!!
