Had pale but definitely there line on FRER yesterday afternoon, came up within a few minutes. Did another FRER with first morning urine this morning and the line was barely there, much much paler than day before (I probably would have just thought it negative if I wasn't REALLY staring at it under a bright light!) and Clearblue digital was negative 😢 I'm 13dpo. Anyone ever had positive test in afternoon and negative next morning and still been pregnant?? So worried it's a chemical☹️
