Most supportive maternity/nursing bra for plus size woman

I'm 30 weeks pregnant and my underwire bras have started to bother me. It's not just the expansion of my rib cage because I wear an extender and I feel the wire cutting into my skin from my expanding stomach. I usually wear lane Bryant bras size 42 DD but I have added an extender to the back in the last few weeks. Can any of the plus size moms out there recommend a VERY supportive bra with no under wire that would not make me look like I have one boob or no bra on.
