Hi Joanne I’m 5dpo and know exactly how u feel, I brought 2 macoms for hospital and 2 from Debenhams ….I’ve only wore my macoms as they are the only ones that fit me comfortably, the 2 I got from Debenhams I carnt even fasten as I’ve swelled that much!!! I measure 30 back so ordered 32 and that doesn’t come anywhere near!!! So for the past 3 days I’ve been sat ordering bras!!!! Still not found one, macom are best cost u only measure size of ur back not cup size xx good luck x
