Like Zorb said that's not actually slow, even as an average. If you look at the last three weeks alone, it's dead fast. (Probably too fast, really, but it's too soon to worry about that of all things since it'll probably slow down again unless you restrict calories too much for your amount of exercise.) 1-2 pounds a week will be the average over the long term for most people who still have more than a few pounds to lose (but not hundreds) and who are able to work out consistently like you are. There is nothing wrong with that. It's perfect.
What may have happened initially is that the sudden changes (especially the increase in exercise) caused water to be retained in your muscles, thus masking your initial fat loss. Now that your body is adjusting (and the fat loss has continued), you are able to see that you are losing, and perhaps even losing some of that original retained water, so you're seeing greater losses. You're not likely to see 3 pounds every week from here on out, but that doesn't matter.
Try not to worry. You're doing all the right things and for the vast majority of people weight loss isn't a magic trick: if you are able to maintain the right size calorie deficit for long enough, you'll see gradual weight loss when averaged over time. Just trust yourself! And start looking for ways to measure your progress that aren't attached to the number on the scale, because that is not going to go down every single week, even when everything otherwise goes exactly as you'd like it to. At 9 pounds down (and probably more than that in fat), you're probably at the point where you're just noticing changes in the way your clothes fit, and so on. You're probably noticing increases in strength and endurance. All these things should be celebrated. Good luck!
