White lines are antibody strips. Here is an article somewhat explaining the whole thing: http://webphysics.iupui.edu/webscience/bio_archive/goodfor3.html
Antibody strips shouldn't be visible but for whatever reason they often are on FRERs. It's one of the reasons a lot of ladies don't like FRERs and don't really use them anymore.
I don't normally use FRERs but I have used a couple here and there. And I definitely have seen some very, very visible antibody strips. One of the tests I opened had a glaringly obvious white line where the positive would be before I even dipped it. Then as the dye ran across the test it sorta lit up pink as the pink dye crossed it and returned to be very white.
A white line is a negative test though.
I'd suggest testing again in a couple of days if you haven't gotten your period!
