nursing bras

So, I'm trying to make some decisions on nursing bras and if they're worth looking in to at this point. I'm currently busting out of a 36E and I'm 34 weeks. I'm definitely just going to continue wearing these bras through the rest of my pregnancy, but just wondered if anyone had any advice on nursing bras once the baby gets here. It's hard to find bras that fit my band and cup size. Do you suggest just getting nursing camis for the first few weeks and going from there? I've heard once your milk comes in, things can get really out of control especially if you get engorged. I've also seen the flexible Medela bras at like target and stuff and wonder if those are worth a shot. Any suggestions are appreciated!
