I went from a 12B to 14DD and have been wearing sports bras to bed since i got pregas as it 'holds' them better and I find they are so sore in the morning. In the first 12 weeks when we weren't telling anyone yet al our friends kept saying...umm Nets your hooters are looking quite big. I wasn't sure how long the new push up bra answer was going to work ha ha...
Anyway they have stayed the same for now but I imagine hey will go up a bit when bub arrives. I seem to have the only husband that prefers them smaller. He is horrified with how big they are now and personally I look forward to going back to a B as well.
