I'm currently 9 weeks pregnant. Happened to glance in the mirror as I was taking my top and then bra off and noticed that in my only bra that is currently at all comfortable: a) my nipples are half out of the cups because it's so small b) it's leaving red welts across my breasts where it's cutting in. I had been in denial about this (for various reasons I'm particularly nervous about this pregnancy and so reluctant to do or buy anything as it feels like tempting fate) but I need to buy new bras, right? But then... do I? Are they going to keep growing (I think my - pretty modest - breasts might have gone up a cup size), and if so would it be stupid to buy new bras now if I'm going to have to do it again later? When did people switch to maternity bras? It feels ridiculously early to do it now!
