Please help me?

Helen

I have five kids already and my last little one is four almost five. My fiancé and I are trying for one last baby and normally I get pregnant fast but this time it’s not happening. We have been trying for about two months. My period is due on the 9th of this month and I took a test this am it was a digital Walmart brand one. It was negative 😭. I have 6 days until my period comes. I have sore breast and I’m always hungry. Very moody. I just don’t know what to do. Any one please give me some advice like should I wait until my period comes or not and test again maybe with a different brand.
