Please Help Me Understand This

My husband and I have been trying on a and off for about a year now without the tracking and what not, and we have had no luck. So I’m trying it this way, But on 1.24.19 I took quite a few tests and they all seemed to have lines VFL, but lines. The FRER

were taken on 1.25.19 and I SWEAR either there’s a line or my eyes are playing tricks on me. But the catch is.. I started my cycle that day. From the 25th until today (I stopped today) and that’s a normal cycle for me. Why would a test show a line if I wasn’t pregnant? I know about EVAP lines, but They were all taken within the permitted time frame and the two digital tests said negative. I’m just not sure how I got lines on tests when EVERYTHING I’ve read has said the only way a line would show is if the test found hCG in your urine.

Maybe my eyes are playing tricks on me and/or maybe I’m still just learning about all of this. But ANY help is GREATLY appreciated. TIA
