i had to guees at my dads side because my grandma and my one aunt both had breast cancer. my other aunt had hers removed because for some reason all the girls in my grandmas family have had it. makes a girl worry. especially if i get those d cups. ( i do realise i sound like a weirdo )

I had to guess my mom's cup size, because like, I don't go around being like "Hey mom, how big is your bra?"....Anyway, I got c cup which I guess is ok I'd rather have smaller though, I'm really self conscious...

I'm a C cup. Thats ok. Though right now I'm 13 and I don't have my period and I am a 30AA (measured with a calculator) but I don't need to wear a bra. How am I gonna be a C cup? I think my mum's like a 34B?

@Hannah, I agree. The puberty and period question was very confusing

I’m turning 13 in a few day but I don’t know what my size i am because the bras I own don’t really fit me anymore and I’m getting new bras before school starts(The bras I own are a 32B). I used a calculator and it says that I’m either a 28C or 28D. My mom is a AAA and I’ve had my period since I was 10. The quiz says I’m going to be a D cup but I’m not really sure if that will be true lol

Every woman on my mom’s side(that I know) are C or bigger and I don’t know anyone from my dad’s side other than his sister who is also bigger than a C.

I’m 13 and 34A. It said I’ll be a C cup. But my mom is 36A. Tbh im not sure 34A is the right size, the straps dig into my skin. But mom’s 36 is too big lol. I already got my period last year, so i dont think I’ll become a C overnight lol.

The puberty, and period question is confusing. bc on the puberty question it asked if you have started puberty, and I said I have for a few years, (I started puberty at 8, and Im going to be 12 in august) but I dont have my period yet, and it said "like I said, I haven't started yet" but you start puberty before you get your period 🤣
