Confusing Tests?

Jennifer
Y'all. Y'ALL. I can't be the only one this has happened to?! I got the First Response twin pack- regular line test, and a digital. I'm 14 DPO, and one day late, so I figured my chances were pretty good, right? I don't see a second line on the regular test. But what's up with my digital? I assume it's invalid, but what the heck?!

I also want to ask my doctor for blood work to confirm either positive or negative. What kind of blood work do I ask for?
Thanks ladies! ❤️
