8 days late, 3 negative pregnancy test.

Dana
So, I am currently 8 days late and I have taken 3 pregnancy test within those 8 days and all were negative! Given, only one of those were takin in the morning time when I first got up. But now I am really starting to wonder. Bc I felt like I was most likely pregnant but then these negative results have got me down. I have a 2 year old daughter and when I was pregnant with her, my pregnancy test showed up positive when I was 2 days late. What's my possibilities here?? Am I rushing it?? When should I try another pregnancy test??
