Hi dognut ....I wouldn't worry about the not pooing and peeing whilst on a walk ...as far as I know this is quite a common thing ..my own dog was the same ..one day you will be out and she will do it , then you will soon be wishing she hadn't started.
14 weeks is still very young ...maybe if you took her outside every 15 minutes or so during the day and stayed there with her until she has done something ..THEN praise her up? Have you had the vet check her over to make sure she hasn't got a urine infection or something similar?
If you do a Search here on Champdogs you can find quite a lot of older threads about housetraining ...maybe something there will help
