I am a 17 y/o Female, turn 18 in 6 mos... have not started yet. Have other development signs...girl stuff, but no armpit hair and no period yet. Docs arent too concerned, I am 5'6'' 90 lbs. Getting a g tube TOMORROW! So if I gain weight, theory is that I will start my periods. I'm really in no hurry!
Be patient, don't worry about 'fitting in'. Life's not about fitting in, it's about being different!
