Irregular menstruation problem
Hi! I'm 15, female. I had my menstruation for the first time when I was 12, but up till now its still very irregular. For example, I get my period once in 3 months, and sometimes even once in 6 months! I get really horrible cramps each time my period comes and I'll feel faint. I even had fever twice and fainted once due to the painful cramps! My friends all have regular periods, and I feel like I'm abnormal or something... furthermore, my breasts don't grow! They stopped growing when I turned 14, and I often get teased at for my flat chest. I mean, I'm not exaggerating or anything, but my breats can't even fit into the smallest bra! I wear those kiddy singlets... I'm horrified and worried. Am I abnormal? What should I do? Is it because of my irregular periods that my breasts don't grow normally?
Some kind soul please help me! Your help is greatly appreciated! Thanks.
