Iโ€™m so confused haha I thought i was going to get my positive at the top (the second one is very close) but then they started getting lighter and now they are getting a little darker. Any advice? Keep testing or take the second one as my positive? Zoom in to that second one though, itโ€™s not really the same darkness
