My daughter is 14 and has not started yet. She has all the signs every month like she is getting ready to start but she has not yet. I have talked to her doctor's office about this and they are like its sometimes happens to girls that are preemies at birth. I don't remember how old I was when I started and I have asked my sister how old my niece was when she finally did and I guess she did when she was 12. Most of my daughter's friends have already started and I am getting a little concerned because myself and my other sister had a lot of medical problems with the area down below. If anybody could give me ideas I would accept all. Thanks

I fear that sheryll is right. After my doctor told me this I make a point of buying organic food. The growth hormone they inject cows and chickens with make girls "mature" faster. they get their periods faster develop breasts faster... but also there is talk about it being linked to breast and ovarian cancer. From hearing that i make a concious decision to buy organic milk.

Most girls get their period around 12 or 13, but it can happen younger or older. Each girls development as each persons genetics and body chemistry. I wouldn't be concerned. My daughter had hers at 12. She came to me the moment she got it, and I was prepared as I knew it could happen at any time. It is important to have a talk with her around age 10 so that when it does happen, she will not think there is something wrong with her, so she will not be frightened. Do not worry, she will get her period in due time, it happens to all girls.

My step daughter didn't start until she was almost 17. She was not too thin to support menstruation. But, the doctors were not concerned as long as she wasn't sexually active. I did get them to run some blood tests on her when she was 16 and they said everything seemed fine hormone-wise. Of course, once she got it, she said she should have been happy to not get it... If my step daughter had been sexually active, they said they would have done more tests to get to the bottom of the matter, but because she was a virgin, they did not want to get too invasive with the testing. They did tell me they would be more concerned if she hadn't started when she was closer to 18...

For the record, in general women need about 18-22% body fat in order to maintain menstruation. So, if her body fat is lower than that, it can cause a delay. Everyone I know who has kept their body fat lower than 18% purposefully is a gymnast, or ballet dancer.

Normal is somewhere between 8 and 20, though some medical professionals will run hormone tests if it hasn't happened by 17. Genetics play a part so if people tend to start late in your or her dad's family that could slow her down. You also need a certain percentage body fat to menstruate so if she's very thin or has a fast metabolism she'll go later too. (that made me not start until I was almost 18) As long as she's otherwise healthy, I wouldn't worry about it, especially since she'll pick up on it and stress can screw with your cycle too.

She is not a a gymnast or dancer, but she does play softball and volleyball. She has no fat on her, but I thank you all for your insight. I know they have done the chromosome test on her when she was about 5 years old to make sure she had all her chromosomes and not missing any. Because when she was 5 she was the size of most 2 year olds and they were concerned with her height and weight back than. So I wanted some other parents insight on this matter. Thank you all for the insight!

I was 15 yrs. old. My daughter started in 4 th grade. I was very small for my age. Actually I think it is a good thing to start later. Most girls now start earlier because of the hormones in food. I found this out later instead of earlier. Actually you must be doing something right.

No problem... i found your post VERY helpful... as my daughter will be 10 this year... and i am nervous about how she will handle "the talk". I do have to admit that it is encouraging that a man like yourself is such a GREAT father. so many women talk about "sperm donors" and such and that's what they call men because... well only god knows why... you are a GREAT peice of proof that they are decent men out there. It isn't as if you are giving advice on breast feeding... you are giving advice on something you dealt with personally with your own daughter... you aren't asking for a pin or medal of honor (like that woman suggested) you were merely offering advice... which like i said i found extremely helpful and encouraging. And as for her personal attacks toward you were rude and uncalled for

My younger sister didn't start until she was 14 so just wait. It's normal. Did she just turn 14? Or has she been 14 for a while? Some girls don't get it until they're 15 or 16. I wouldn't worry too much yet.

She will start when her body is ready, and she will have many years of the "curse" so I say embrace and enjoy, soon enough Mother Nature will be knocking on her door monthly

My daughter is 13 1/2 and has not started hers yet. Everyone of her friends have so she does feel a little left out. My other daughter started hers a week after 14th birthday. I was almost 13 when I got mine. So hopefully she should start soon and all will be well.

My daughter was 14 before she got hers, even though I had gotten mine at 12. There's a large range of "normal". If medical issues regarding that run in your family, make sure the pediatrician is aware of them. But if he/she knows and is not concerned, then you probably shouldn't be concerned either. One rule of thumb: most girls will get their first period within two years or so of when they begin to noticeably develop breasts.

There is no "normal age" really, because every girl is different. I didn't get mine until I was 15 - I was a very slim teenager, and never even grew boobs until I was 14. My cousin was 17 before she got hers. But I also had friends who got theirs when they were 9 or 10. I wouldn't be concerned at this point. In fact, I would tell her to be thankful, LOL. I was always thankful I didn't get mine too young, because then it was a pain in the butt with my sport and other activities :)

in another post you mention your daughter is thin... this has alot to do with it. she might just start later since she is thin... don't rush it... don't worry about it, it will happen, then you'll wish it hadn't yet
