Pregnancy really does change a lot with a woman's body! I try on 7 of my old bras that I've had over the years and show how they "fit" on my growing boobs. I went from originally a 26J (DDDDDDDDDD cup size) 40" bust to about 45"- 46" bust through my pregnancy; I cannot find out what size I am, as the US does not go up that high for bras. The closest I have found to matching my size would be a 28Q or 34P. I'm certain my breasts will get much larger as I start to lactate in the coming months.
