I'm starting to notice a purplish-stretchmark-looking ring around my nipples that is from where the plastic pump flanges are. I'm been pumping every 2-3 hours for the past 2 months, so obviously these marks are from the pump. Is this normal for those who EP and will they go away?
Re: pump marks?
Cup size doesn't really matter with what the flange size is. It has to do with your nipple size as you're pumping.
How are you holding the flanges to your breasts as you pump? is it possible you're pushing them too tight? If the pump feels ok on your nipple/areola area I don't think you'd need a bigger flange sizes. Do you have a lactation consultant you can ask to look about your flange size?
