Thought I had the flu..

Turned out it's a baby!

I know you're supposed to wait to take an at home pregnancy test ... But I took one (I have had about 48oz of water) and it came back negative. I'm hoping and praying that it's bc my urine is diluted... This is my 2nd pregnancy and the first one we found out when I started to have a miscarriage so I never took the at home test.

Any thoughts or advice?
