Positive? Negative?

My periods have been irregular for the last 17 weeks -- ever since a pregnancy loss @ 22 weeks . I have been testing @ 6 weeks just to make sure that I am not pregnant. Yesterday I tested and got this faint vertical line. With our first pregnancy (the baby we lost) the vertical line was solid & the horizontal line was faint. So I just don't know what to make of this? I retested today w the morning pee & I got the same results. I plan to retest on Monday w a digital!
