I have been using nb for almost two months and barely just started to swell. I would swell for almost half a day. Maybe you just need to pump longer. I also notice that I used to pump everyday for like two to three hours and get the great swelling for a long period of time. Now I barely pump an hour every other day and my swelling last like lest than two hours.

This is my experience so far. Hope this helps. Sorry about your situation and please do not give up soon.
