Using first response rapid results

So I accidentally grabbed the Wong test at the store. The rapid results is supposed to show results in 1 min at the time of your missed period. I took the test 2/3 days before my missed period and got a BFP at about 5/6 minutes. It says don't read after 10 minutes. I've taken 3 test in the last two days and they all have a pink BFP. Would this still be considered pregnant? Or should I take a early response test?
