One step pregnancy tests, bought 20 off of eBay, first used Friday and negative, yesterday couldn’t decide if it was negative or evap lines (3 out of 4 had faint lines, this morning used fmu, 5 tests all have a faint line, like really really squinty…done a frer and I’m not sure if there’s a major faint line or if my eyes are playing tricks because of the one step ones…anyone else had this? Are the one steps reliable, would I get evap lines on all tests in the exact same spot?
