Nursing bras?

Jessica
Any recommendations for a supportive nursing bra for a large chest? I'm a 38DD and I bought an underwire nursing bra from Target that was great but after a few days of wearing it I got a plugged duct right where the underwire hits. I'm an LVT at an emergency hospital and I work 13 hour shifts and before I wore a compression sports bra but I'm afraid that won't work now either. Any suggestions?
