Hey Ricky, all of this is thoroughly normal. Switching from two crutches to none immediately is probably not good to do. I went from two crutches, about one or two weeks on one crutch, then no support, but still limped a bit until my hips got strong enough.
First, don't measure your progress by anyone else. We all had our recoveries at different rates, the only thing is your goal - to be fully functional on that hip in a year or so. For anything else you need to listen to your body, to look at your own progress based on how you feel.
Clunking is a fact of life for most of us during the first year. I got it quite a bit when I was where you are. It just means that your supporting muscles are not strong enough to keep tight control on the prosthesis yet. That's fine, it's what you're working on with your exercises. Check all of our comments, stories and you'll see a large number of us talking about clunking. We talk about it almost as much as TEDs and ROM.
You're fine, exactly where you should be, given that you're just freshly getting off the crutches. You'll have trouble with stairs, etc. that and the clunking will reduce and go away.
Patience is the worst for all of us, but you are in this for the long haul, so relax and let your recovery happen.
