Vent/Question

Aims

So. I couldn’t help myself and bought two of the .88 cent PT from Walmart. I took one this evening and it was negative. AF due in 5 days. I know it’s still early but in the past I used a First Response and got a positive 5 days before AF. I am a really impatient person. And now that I have a second one I will most likely take it tomorrow morning because it’s here and I have no self control. I just want to know as I’m sure most of you ladies do as well. The original plan was to wait until February 1st 2 days before AF but like I said I have zero self control. If I were to save the test I have until Friday would it pick it up or do I need a first response one??

Thanks
