I think im currently about 12 weeks pregnant (not sure still waiting on scan). My current bra's are begining to get really uncomfortable so im thinking of getting some maternity underwear. I'm stuck with what style is best to buy, if i buy a nursing bra now will this last me all through pregnancy and for breast feeding or am i better just getting a soft cup bra for now and nursing bra's later? I just don't want to spend money if i dont need to.
