I started working agaib last week and i am pumping 2-3 times at work and once before I leave for work, today i pumped total of 4 times. My right breast is tender and still feels fuller. Last pump about an hour ago i was able to get 4.5oz from my left but not even 3ozfrom the right. My left normally produces more so thats no concern but this fullness/tenderness is new today. Could I have a clogged duct?
