Two positive and one negative test.

So I've felt like poop all week. Monday I took a internet cheapo and it was negative. Today I still felt like poop so I took a second Internet cheapo and forgot about it. After I finished getting my son ready I went back to my bathroom and saw a positive test. I couldn't believe it. So I dropped my son off and rushed and got a fr combo box with a regular and digital test. I took both. The regular test came back a very very very faint positive and the digital came back negative. I'm now very confused and heart broken. Are the digital less sensitive. I didn't get a change to take a pick of fr, but here is a pick of my internet cheapo.
