Do maternity bras come in all sizes? I am four months pregnant and have just grown into a B cup for the first time in my life (I'm 30 so it's been some wait)! I have hovered near the maternity bra section but I'm a bit worried that I don't have anything to fill them with yet! I'm not sure whether to invest in maternity bras or keep buying standard bras as I keep growing (my mum is a DD so what if I catch her up?) ;-)

Any advice from any other girls new to having a cleavage would be appreciated. ;-)
