Well yesterday I got af (so I think) but I decided to test just because it was really weird for me and I did get a line but so light I called it an evap. Well today I test again and I get a darker line on the wondfo to where it will pick up on my camera now. I did take 2 other brands of Ics along with the wondfo this morning and there are faint lines on them also. but the only one that shows is the wondfo one in the pic. So tell me ladies what do you all think.
