Hi cowgirl,
I doubt you are doing anything wrong! Lots of people see no results after a month - remember that it isn't swelling you're after but permanent growth, and that takes time. There isn't a standard "proven method" as there is a very varied approach - from noogling for 30 minutes up to 6-7 hrs per day, from doing it twice daily to once a week, noogling with water, using pump and hold, pump and release, pump and hold for 7 minutes, release for 2.....The list goes on!! Give yourself a few more months for those cells to divide and create permanent growth, make sure to measure and/or take pictures at the same time every month to give yourself something to compare with. Because we see them everyday, we sometimes miss the changes with our bare eyes. Best of luck to you
