A BFN after 3 BFP 😨

Nayab
Ugh... I'm seriously on the verge of tears. I just retested because I wasn't feeling "pregnant" anymore last night and I got a BFN. I'm 4 days late.. I took a pink dye, blue dye, and a digital test that all said positive. 
And now I get this...😭
I'm not bleeding or spotting. I don't understand 😪😪😪
