This is kinda an awkward question...

Yes! When u hit ur period u start puberty! And don't worry about getting it at 11! We all get it differently! Maybe some of ur フレンズ hit it 13 (that's when I did) others 10, and even 16! That means ur an early bloomer! U should not be worried.

When あなた start your period - that's puberty. If あなた don't have boobs yet; it's unusual not unheard of. あなた would've had symptoms that あなた wouldn't have recognized as puberty as well. Also, 11 is completely normal and is actually the average age for girls to get their periods these days. I was barely 11; while my best friend was 15 (lucky girl!) so あなた are normal. Some girls start at eight years old.

It's okay, puberty starts at different ages depending on different people. I'm 11 too and I started my periods when I was 10 as well. You've started puberty at a young age and that is completely normal.

I began my period when I was 11, too. A girl's/young woman's period is a clear indicator of the start of female puberty. No worries, dude. :)

ive had mine for 3 years now
began when i was 10...

Starting your period is part of being in puberty. Your hormones start 芝居 on your body before あなた even have physical changes. You're on the younger side of "normal."

well, someone i know started at 11, and i started at 12, so... it's normal! 'cause nothing happened. although, you're supposed to get cramps... (so i've heard) i do, though.

Don't worry ,I started my period with 9(I'm 13 now) and it's very normal.Some girls start early and others later.But if あなた 星, つ星 early ,early あなた will finish.

Dont worry! My mum 発言しました that あなた can have your first period when your eight! And puberty starts when your around 11 または 12 years old! Talk to your mum! She can help あなた LOTS! My mum didnt though...
