My sister did it at 7 weeks, the earliest it says you can. It said girl and she had a boy. I did it at 9/10 weeks and it said boy and I have a boy. I’d assume it’s more accurate the longer you wait. When I did it, the directions said not to do it prior to 9 weeks- this was 4 years ago.
Just did it—it actually said you could test as early as 6 weeks. I tested at about 7.5 weeks, and reportedly…we have a girl bean The testing we have queued up at 11 weeks will confirm or refute—will follow up to let you know if it was accurate!
super late to this but me and my sister tried the ramzi theory with her last 3 and all were accurate, has super good reviews too, i tried it this past weekend and the prediction was a girl but i won’t know forsure until my 20wk US
