Ovulation test to predict pregnancy?

I have left over ovulation test from when I started testing this month. I got positive results on May 12+13 and BD on the 12th. I dont wanna waste my pregnancy test as I'm only 7dpo and my period isn't due for another 7 days. I took one of the ovulation test today and there is definitely a line but its faint, you can see it without struggling tho lol could that be a good sign?
