I have breast buds. Yesterday I found 3 or 4 dark hairs. It's all really confusing. No under arm hair. I shave my legs. My mom got her first period a month before her twelfth birthday. I had my thirteenth birthday and still no period. I so confused! Why haven't I had mine yet? I'm not sure about when my dad did, but I'm not going to ask.
Everyone develops at their own individual pace. While children tend to develop in a similar pattern and on a similar timescale to their parents, it is not absolute because you have a different mixture of genes from your parents.
Girls will start their period in either stage 2 or stage 4 of development. It runs about 50-50 between which stage you start in. It sounds like you are in stage 2, so it may happen soon or it might not happen for another year or more.
