help!!! 3 days late & negative tests

Theresa • Hubby & I are expecting! October 18th, 2018!
Long story short my periods have been regular since I was 12 years old. I had a miscarriage in December , but as soon as that was over my periods were exactly the same again(surprisingly ) now this month , I'm going on my third day late, and I have taken  (all clear blue) 2 digital, 2 regular (with lines)... 
All I'm left to do now is wait and try not to get excited!! Any advice, lovelies?!
