Why would it do this???

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Has anyone ever have this happen???? 1st one is 88 cents, second is first response digital, third is equate taken 1 hour ago. What is going on and why do 2 say bfn and one a positive?? Equate was a huge bfn an hour ago, I took the other two 30 mins ago. I feel sicker than a dog, sweating all day while cold, off and on nausea constantly, dizziness, 2 days late on af.... I'm so confused, my poor husband let me freak out and just cry and cry. :-( I'm about to give up.
