I started NB a 32B and started with the medium domes, was able to get use out of them for a good 2 months before needing the large, then used the large 3 months then moved to XL. So I'd say give the mediums a shot first. It's easy to over pump with the larger domes and that CAN damage your breasts, better to be safe than sorry. My rule of thumb... if when you pump it is hurting your breasts, you are over pumping, it should feel tight, even a lil discomfort, but NOT painful! If your breasts turn purple, you are over pumping, over pumping meaning using too much suction, not the time of pumping, though I've never went over 4 hours straight of pumping. I pump and hold and when I go longer than an hour I do not use as much suction as I would for a 30 min or hour session. Use PLENTY of lotion! Can't stress that one enough. If you get blisters or red dots on your breasts, you over pumped and that's the first signs, just take a day or two break then try again. Noogling is a timely process it will not happen overnight and you don't want to push yourself too hard. Good luck!
