Faint line but not pregnant on digital?🤔

Katie

So, top FRER was taken yesterday afternoon, middle FRER was taken with FMU today as well as the clearblue Digital. I’m getting lines (I think?) on top 2 FRER tests but clearblue says “not pregnant”? Also, those lines popped up maybe 30 seconds into testing? Hmmm...anyone have any idea what the verdict is here? Pregnant vs not pregnant? 😩
