I've just been out and bought a new bra as I've gone up a full cup size now, but a friend has just told me that you shouldn't wear undrewire bras while pregnant as it can cause problems with the development of your milk ducts (or something!). Is this really the case? Is is OK to continue to wear underwires for the first few months at least? All that the books say it to wear a good supportive bra...
Thanks for your advice!
