What the ?!?! Update

So two days before Christmas I get 4 positive pregnancy test but then I take another test to give as a gift on Christmas and it’s says Not Pregnant?!?! I have been taking one test every morning and all are negative!!

Ps the clear blue was the later test.

I deleted the rest of the positive photos do to how upset I was.

Just my luck I get faulty test?

I’m 7 days late.

Today’s test 2nd of Jan

New test, do you see a line? I’m so confused!!
