I started right before my 14th birthday but I was normally very very thin like 93 lbs at 5ft 6, which they say can affect your period. My dtr showed signs at 8 and got her period at 9 1/2. She is 5ft 2 and about 135 lbs Once she got her period she never grew an inch taller. She went from being one of the tallest in her classes to one of the shortest. |
