Pink Vs Blue!

I took a pink test this morning and it gave me a vvvfl. But it’s definitely there. Confirmed by the Glow community too!

I saved the pee in the cup, then went to Walmart several hours later and got a Blue test. Tested the same pee from the morning. Negative. Do you think the pee’s freshness matters? Is it the test or the pee?

Thanks gals
