I do the massage setting till the milk flows then switch to the pumping setting & pump till it says 10 minutes. When I was exclusively pumping I did 15 minutes pumping every 3 hours at the time I was creating an over supply x When I feed on the breast I use the haakaa on the other side, usually 15 minutes.
I'd really recommend getting a Hakka. Use it on the other boob for collecting the let down, especially 1st thing in the morning. In the shower works well too.
I’ve been told that 15/20mins pumping every 3/4 hours is good enough from the midwife but I suppose it’s down to you really and how much your little one is feeding. Also if your boobs is hard, and blocked ducts ect If in doubt get in contact with your local BF support team who can shed some light on it for you x
i pump after feeds for about 30 mins, and use a haakaa on the opposite breast when feeding
