This chart should help people who are palpating but aren't sure what the follicles they are feeling mean for their girl's developmental stage. I made this for a video that I will be finishing soon on palpating. Of course, nothing is exact without an ultrasound machine and even then things can be difficult to find. I hope this helps! Feel free to share it :)
