What does a white line mean?

Hi all,

We have been desperately TTC these past 2 years. My husband has a low count but has been taking hormonal therapy after they did a procedure on him to remove varicose veins on his area. Both have improved his count but try and try again & we can’t seem to get our BFP. This time around I’ve been having a lot of different symptoms. I’m 1 day to AF and I got this on my FRER.... Does anyone know what the white line means?
