You are doing fine. Average losses for women are .5 to .75 lbs per day. You're average right now is .73 lbs per day. High end of average.
It is typical to see stalls, etc during the latter weeks. Week one is whirlwind with good losses and then we get blindsided by the slow down to a more normal pace in week 2 and beyond. The body takes a breather to catch up from those fast losses.
Keep going, you're right on track.
