Okay so I am thirteen years old, and I got my period almost exactly two years ago. I am about 5 foot 6 and I weigh 60kg/132lbs (that is approximate- I probably weigh a little more.)
I'm not fat, but I'm definitely not skinny- I'm somewhere in the middle. However, I am really flat chested. (I don't even wear a proper bra yet- I wear a crop top)
Even though I started my period two years ago, will my breasts continue to grow? Will they ever get bigger? Someone told me that a way of telling this is if they hurt, but I don't feel any pain if I squeeze, push or lay down on my breasts.

Thanks.

P.S My Mother and Grandmother on my Mum's side have REALLY big boobs, so I always thought I would too. Will the fact that they have big breasts impact whether mine get big or not?

They keep growing till you are 18 or so. Everyone grows and matures at different rates.
And you need just to stop worry and listening to people who have no idea what they are talking abuot.

I remember my period came before my friends' did (boy was I upset about that) and I was totally flat for quite a while, while they had almost fully developed breasts. There's no rules about puberty. Just tons of variety.

Although genetics always (unless it's a mutation) has something to do with how we look, you just don't know how much and which genes you get from each parent. Chromosomes divide equally, but not genes.

There's nothing you can tell from how much they hurt.

So true, genetics often surprise us, and often we do not look like our parents but another family member or no known member, from some trait long hidden.

My wife for example, her mom and dad are skinny, mom flat chested, well my wife is far from flat chested, in fact she had to have surgary to make hers smaller, they were so big. Well the only family member like that was a sister of her grandmothers.

So just because parent looks a certain way, has little to do with our looks.

Your body, including your breasts, can and will change all your life. At your age and stage of development I was a 32 A. By the time I graduated college I was a 36D. I did not get fat - I just rounded out. Most women will end up around a B or C.

In any event, love who you are. Accept what's beautiful about you. Seriously - it's such a waste of time and energy to start nitpicking your body at your age because frankly, there is beauty in every body. The most beautiful are the healthy, well-cared for bodies so if you want to be beautiful, take good care of yourself.

Your question reminded me of a conversation between my long-time friends at a party recently. We have all known each other since we were your age but we're all close to 50 now and we can say just about anything to each other. We were debating the merits of large vs. small breasts. The men came to a consensus on the topic... "we need to see and touch all of them to make a decision". Of course, this was a joke but the point was not lost on any of us - men like breasts of any size and shape. There are some men who like very large breasts, but just as many preffer smaller ones. As a woman there are advantages to both. I often wish I had smaller ones because I run and play sports and DD breasts are not exactly comfortable for these activities. I also envy my smaller-breasted sister her ability to wear little tank tops and backless evening gowns - never an option for me. On the other hand, she wishes she had larger breasts because she thinks men like them better - she's always had boyfriends and has been married a long time, so - whatever!

You get what you get - take care of it, and you'll always be beautiful!
