UPDATE- pink dye and digital said not pregnant, what do I do now?

I'm due for my period on the 21st and I been feeling off and just not self, I went and grabed a test because I had a weird feeling. I'm six months post partum with my second child. I'm freaking out, im on the pill aswel, this test looks exactly like the one I took when I found out I was pregnant with my son :(
