Not sure what to think about BLUE DYE TEST😭

Laura

Ok so please tell me what you think. I’m 13dpo today and for the last two mornings I’ve gotten a super faint positive on a blue dye and a stark negative on a FRER. After hearing so much about how blue dyes give false positives, I tested one with water to see what would happen and I don’t see anything. I’m losing hope though, because I figured for sure the FRER would pick something up by now. Do you think I’m out? My bbt temp is still elevated as well
