Help!!

So I had unprotected sex twice when I was ovulating he pulled out but I know that’s not a reliable method. At 6 dpo I randomly spotted for a couple hours and have been cramping the past two days I took two blue dye test yesterday. And faint lines came up within 5 mins. But I have read that they can give false positives. My period is not due until 8 days so my cramps should not be this early and they are not a bad as period cramps.

What do y’all think of my chances??
