Constantly testing! EDD 7/8/16

Gabby
I got my first positive on Monday. I was obviously in shock so I took 2 more tests that night and they were all very strong BFPs
Since then I've been taking a test every morning just to be sure this is actually happening! I feel like I'm going crazy, all my tests have been super strong so I don't really know why I'm freaking out
According to lmp I'm 3weeks 6days
My symptoms are light nausea and light cramps, backache, acne, always hungry and swollen boobs!
Anyone else can't stop testing? I'm going nuts
