Personally?
I wouldn't bother with digital tests. From my experience, they are crap. I was 12 weeks pregnant, and I knew it, when I took a digital test, coz it was there and would have been wasted if I didn't use it.
So, at 12 weeks pregnant, the digital test told me "Not Pregnant" which put me in a panic thinking that something had happened to baby. Well, baby was fine, the test was just dodgy.
