[My Name is Autumn]

I'm normally a (32) C cup. But sometimes I'll look in the mirror and say, "whoa, where did THOSE come from?" then i'll measure myself to be a 30 D! this normally happens about one or two weeks before my period. My breasts swell up to the size of balloons and they get heavy, full and round. Then, during and after my period, they go down to regular size. Is the sudden bloating in my breasts coming from my period? And if so, any idea as to WHY? Because I've talked to my cousin about it, and she thinks i'm weird because she's never experienced "balloon boobs" before her menustraul cycle. any ideas?

Your hormones are very strong during your period, causing your breasts to swell. Your hormone level goes down during your period and shortly afterward. You may have to wear a different bra during times that they are large. BTW, I think you meant something other than 30 D, but I don't know what.

Your breasts do change with your menstrual cycle, but the degree that they change is individual to each person. Mine tend to get fuller (not really bigger, they just feel fuller) and my nipples are more sensitive during the week I ovulate. If you have reason for concern though, it never hurts to ask your doc about it.
