Weight loss during first few weeks?

Hi all - just getting started as I've lost a stone on SW but my losses have stalled and i've previously had more luck with calorie counting. I'm 5'2" and 12,7 but I want to be 9,0...so 3 stone 7 to lose. I'm on 1200 cals per day and I'm happy with 2lb per week especially for the first stone or so, but interested to hear if many of you have gone over and above the 2lb per week during your first few weeks? Thanks
