When I had to give up bf at 5 weeks, my doc told me to start my normal contraceptive pill again. From memory, I think I only had to express a tiny bit for a couple of days, just when it got uncomfortable and then it was okay. Has anyone esle been told that the pill will dry up their milk? (Not mini pill, I had the triphasil)
