vvvfl or line eyes

It's 4 days before expected Af by glows prediction but I think I can see a start of something. This past week I have looked at so many tests I could be wrong. Pic was taken at 3 min and it got just a little bright after 5. The instructions says not to read after 10 so I threw it away to keep from doing that. The line is very hard to see but my husband and I see it. I am so stressed. I got two False positives 6 days ago. One negative 5 days ago Blood hcg 4 days ago was only 1 and this today
