2 pounds a week?

You're fine. More than 2lbs a week is hard on the body; when you are pushing and depriving and grinding at it with not a large amount of weight to lose.
When I started (in July 2015) I was 290lbs, I'm now 208 lbs. If you divvy that up we're looking at an overall loss of 3.5 lbs roughly per week. Some weeks the scale hardly budged; other weeks I'd woosh 5 or 6 lbs across a few days. It's slowing down somewhat now, because I have less mass and my body is more expectant of the eating and moving it has gotten the last six months but at no point did I skip meals, go to bed hungry, have ridiculous workout regimens or anything else that would indicate poor/unhealthy choices.
Your body is rejoicing in the better lifestyle you're giving it; as long as you keep in mind that the quicker loss is a bonus and try not to force the same pace once it has tapered off a bit, you have nothing to worry about
Good luck!

Weight also does fluctuate throughout the day up to a few pounds. Salt and water intake, urination and bowel movements, and even eating a big meal all cause fluctuations in weight.

A lot of that would be water weight so I would not stress. Have you taken your measurements?

Also it's safe in Australia to loose a kilogram a week which equals to about 2.8lbs. I would not stress. It may slow down. Weightloss always shows bigger numbers at the start, the hard part is the plateaus. That why it's good to go by measurements and clothing size. Even though you may not be loosing on the scales you are most likely still losing inches. Goodluck

I started at 213.5 and am now 198.2. I've been trying to lose weight for 33 days. I saw my doctor last week and told her about my plan an she said it was just slightly over average for someone eating 1200-1400 calories a day and working out 3-5 days a week. She said I was fine

You'll lose a lot initially if you have a lot to lose. Don't let it scare you. You will start to lose less and less as you start to get closer to your bodies standard weight. I'd be more worried about plateauing than your fast loss at this point as long as you're staying within you allotted caloric deficit and it isn't set too aggressively. I would recommend adding in a heavy lifting program to take advantage of your extra weight now and gain a little muscle to fill in the gap left by the fat loss. You'll thank yourself later.

With me, it usually evens out. I was losing at a rate of about 1.5 pounds per week for about a year a while back. Some weeks I would gain 3 for seemingly no reason, and the next week I would lose 5. I've got an excel spreadsheet that I track the weight with and how many weeks, avg per week loss, BMI, etc. As long as the numbers average out, then I wouldn't worry about it just yet.

Seriously, It can be dangerous. I lost about 60 lbs in less than 3 month (about 5 lbs a week) and I did have some serious serious problems that kept me in a hospital bed for 10 days. I almost died. My advice is listen to your body and if you think you are losing too fast just consult your doctor. DO NOT take chances. I know there are shows like the biggest loser and some people can do that BUT if you are not sure, just ask your doctor.
