I'm 19 y.o and I haven't had my period for 11months:( I started having period at the age of 16 and even before its so irregular. Sometime I'm 2-6months delayed but now is the longest for 11 months. When I was 6months delayed I consulted to an obgyne and did some ultrasound.the dr said that nothing is wrong its just that my ovary is still immature.is my case normal?:( I'm worried if this condition may lead to inferrtility:(
