I'm about as new as you...I started seeing swelling right away. But I pump them up hard until I feel a lot of pressure. It won't take long before there is no pain or very little. Hope that helps!
PS I've found that putting lotion on before pumping or even heating your breasts a little (heating pad) will get them to swell.
i would suggest building up tolerance slowly, 2 years in and im a b cup from zero, as they say its a marathon, not a sprint. if you over do it in terms of too much pressure you will cause damage, which then sets you back.......................
