BFP yesterday but...! please read?

I laugh, only because I used these same test strips. In my case I took a test every morning. After daily bfn's I accidentally left it on the counter as I took a shower, when I was out of the shower I realized that the line did show up. I went back through the trash (gross I know) and sure enough from 5-6 days before my period was due there were the same faint lines I was able to compare the strips from the days and see the difference in the strength of the lines. If you give it a few more days you will notice the line become darker. I 100% believe that you are going to be a mommy. ( I loved those test strips, they do exactly what they claim...early detection)
