My period isn’t going to show up in another week or 2 and I’m 9DPO and I took 3 first response tests all came back VERRRYYY faint within 3-5min and I took a gas station $1 test and it came up negative even checked it the next day and it was still negative no indent nothing.. I was wondering does first response pick it up better than a $1 test? Or does the first response give false positives like the blue dyes do now? This is my test from the first response
