I visited the doctor for a routine check up about my contraceptive pill, and the doctor seeing me asked me many questions about it and how I was reacting to it (it was a new pill as my old one had given me lots of side effects including tiredness, headaches and mood swings). He then said "the last doctor has written pfw - do you know what this might mean? Obviously I didn't and left the surgery, quite happy, but wondering what pfw meant?!!!
any ideas?
