Freaking out

Katey
I made a post earlier today with a blue dye test and a majority of women said it looked positive but it was barely there. I actually thought it was negative. I just took another and instantly there was a line but it wasn't blue. It was more of a gray color and it wasn't super thick it was sorta thin. Has anyone had this happen with blue dye and it was wrong?? I am seriously freaking out. I am on my way now to get a pink dye. I love babies and I have a son but I seriously can't be pregnant. I am on birth control and I never miss a day! How is this happening?!
