AF due tomorrow, or nah?

I took a first response test yesterday, came up negative. It was after nap pee, almost clear pee. I usually have a little spotting by this time, but there's only discharge. Hubby swears that I'm pregnant, so he just went out to pick up more pregnancy tests with a coupon I had. When I was pregnant with my son, my positive result was VEEEERY faint the day AF was due. I'm testing in the morning. Fingers crossed! 🤞
