Yes it is normal, some people develope slower than others. Dont worry until your 16 then you might want to talk to your docter about it.
It is possible if you have not started your period yet, you may be fixing to start soon.
Once a girl has started menstruating, her period should come about once a month and will last for about 5 to 7 days. Cycles vary, though, and what is "normal" for one girl will not be "normal" for another. Some girls have very regular periods and will be able to calculate exactly when their bleeding will start and finish, while others have more irregular cycles and it can be difficult to pinpoint exactly when the period will start and end.
well i dont judge but you shouldnt be having sex at such a young age. first doesthe 9 year old im guessing this is the girl have her period. once a girl has had her period she can get pregnant but it all depends on if the guy has gone through pubertyso if the girl hasnt gotten her period yet the answer is no she cant be pregnant. but if she has gotten it and the guy has gone through puberty yes it is possible for the girl to be pregnant. if the guy hasnt gone through puberty once again the answer is no. so she can only be pregnant if the guy has gone through puberty and the girl has gottenher period.
Yes
Answer:Well I am a very muscular girl. I am very competitive girl (I am not "normal") And I weigh 106 pounds. So a "normal" girl should weigh about 90 pounds.Well ok this is a second answer.....but im 13 and 5'7" and I weigh 130. So I've started my period and it's normal to loose and gain weight and that's what happens, but im a competitive dancer. So i have alot of muscle, and I eat healthy. I also have not weighed myself since I have started my period.I am 5 foot 7 inches, 12 years old, very athletic girl who has not started my period, but eats healthy and I way 115 pounds. If you have started your period you may way less because of loss of baby fat. You may way more because you are not active, you don't eat healthy, or you were on your period the last time you weighed yourself so you may have had excess fluids.
No. If you haven't yet started your period, it means that you haven't yet started to ovulate. So, you can have babies yet.
Yes
Eleven years old is in the normal range for a girl to start getting her period. This is a normal and healthy part of female development. Some cultures celebrate a girl's first period with a feast or ceremony.
I don't believe she needs to go to a doctor, its a normal thing for a girl to have her period. Unless there is problems, then yes I suggest going.
it is so normal i started to think about stuff like that when i was 10
the normal ages are 8-15 the average is 11
Yes, especially if you've started your period. They're growing, that's why they're sore. Hope they don't hurt too much :)
