What’s the earliest I can test with a dollar store brand?

Rhonda • I have two beautiful children ages 8 and 5.5, Married to my best friend ❤️

So the last 3 days I have been extremely tired, and very nauseous, it’s been throughout the day and worse a few hours after I eat. Hubby and I are trying for baby number 3 for 4 years now. I have been feeling a lot like I did when I was pregnant for my son. Fingers crossed ladies Aunt flow is due the 23rd.

My question is what is the earliest I can test? I have been having cramping the last day or so as well.
