False positives? Is this possible?

Beth • Newlywed with 7 and 2 year old girls .. trying for #3
Okay, I have taken 7 FRER and all are negative.. But EVERY blue test I take is positive.. target; Walmart, ept.. Etc. are these all false positives since FRER is showing nothing? All of these pics were taken within 5 mins and within the last 2 days.
