Hey there Ali
Similar size to you 14d pre pg and now and 16E. I find that maternity bras feel like you are flying in the wind, so i always wear a b/feeding singlet over the top- the ones with the inbuilt bras- That way you have double support. K-mart sell b/feeding singlets with a shelf type of bra thingy for around $16 each- they have the slits so bbs can come out of B/feeding. I found that last pg- i always would wear a singlet top under my clothes and bubs were constantly pulling at your top and exposing me- so stopped the embarrassment of me being flashed at everyone!
HTH- materinty bras take a bit of getting use to but wearing the extra support in a singlet top does make a difference
take care
