Walmart tests?

I'm never ever late on my period, glow is always extremely accurate for me and so far I'm 3 days late. The day i missed my period i got a negative result on the walmart 88cent test. We are trying, but it's only been one cycle and we didn't try very hard...either way, I'm just wondering how accurate these little cheap tests are. With my first I binged on those expensive first response ones, not doing that again haha.

Took a first response, positive!!! Oh my...here we go again 🎉🎊😭😁
