Ladies, I POAS this morning with FMU using a FRER. I kind of already know it would be negative but my AF hasn't arrived and I'm waiting for first normal AF after MC (I know it wouldn't probably on time this month due to my MC).
But I noticed the control line looks funny compared to what I'm used to. It looks a bit jagged to me. Is it how it is with FRER now or is my test defective? 
I am a bit worried if it could be defective cause I bought quite big batch with this one online.
