Best pregnancy test

I know this sounds like a stupid question but what is the best kind of pregnancy test to use??? I tested on Sunday evening and again using fmu today (Tuesday) using First Response. And I don't know if it's just me but I don't like the curved handled ones because I thought I saw something and then if I moved it was like there is nothing there at all. I just bought True Blue digital, but I don't want to test again too soon and waste a test for nothing, or if there are better tests to use. My periods have never been regular off of birth control so I don't know when it's supposed to arrive for sure. It's "later" than its been the past couple months but not as late as its been in the past. So any advice is appeciated. Thanks in advance!
