Am i losing to fast?

Am I understanding this right: You've lost 19 (or 13?) pounds in 57 (or 40?) days (I'm not sure whether your 40 days and 17 days overlapped or not, same for the loss numbers). No matter how I parse it, it looks to me that you've lost somewhere between 1.6 and 2.5 pounds a week, on average, over 40 or more days.

Yes, it's possible that there was some initial water weight loss that made your loss rate look faster. It's also possible (especially if you're premenopausal) that normal water weight fluctuations made your loss look slower or faster somewhere in the relevant time period. Weight loss is always uneven/non-linear. That's why it's good to look at the average over a longer period. 40 days is a fairly long period.

If you've lost 6 pounds in the last 17 days, that's still about 2.4 weeks, and about 2.5 pounds per week on average. Unless you weigh over 250 pounds, that would be fast weight loss, probably too fast for minimizing health risks. It would imply that your maintenance calories (to maintain your current weight) are 1250 calories a day above what you've been eating on average.

If you're really losing at that rate, with MFP set at a 1.5 pounds/week goal, then you should be fine if you reset your goal to 1 pound a week, or possibly a slower rate even. If you eat more, you may see a temporary scale jump from extra carbs and extra digestive system contents. Don't let that panic you, it should sort itself out in a week or so. Even if you're losing at 1.5 pounds a week for real, you still have room to eat more, and lose.

The calculator estimates (like the one MFP gives you) are not accurate for everyone. They just spit out the calories it would take for an average person your size/age/etc. to achieve the target weight loss rate, based on large-scale studies and formulas. Most people are close to average, but most individuals are not exactly average, and a very few can be quite far from average. That's why it's important to trust your own data, once you have enough of it to get a clear picture.

If I believed MFP's estimates for me, instead of maintaining my weight now, I'd still be losing like crazy - its estimate was way too low. When losing, I lost too fast at first on its estimate, and the results (in energy level and strength) were Not Good. To require lots more calories than MFP estimates is quite unusual, but it can happen.

I don't think you need to worry. We are all different and even though 1-2 pounds a week is considered the (right amount), you are definitely on the road to better health once you reach your goal weight. Many of us underestimate our daily calorie intake because we do not accurately weigh our foods and forget to add our salt intake. Your body will balance out the weight loss and plateaus in our weight do occur even after strict adherence to strict diets. We must change things up and exercise more to get great results. Calorie restriction and intermittent fasting gives quick results so keep up the great job. My goal is to lose 2 pounds by August.

A lot of the initial loss can be water loss if you changed your eating habits or macros, for instance if you're eating less carbs.
You may also not be as sedentary as you think - sitting with a group of preschoolers seems a lot more active to me than sitting on a couch watching tv.

You say you have 50 to 90 pounds you could lose to get to a moderate BMI - the more you have to lose, the faster the weight often drops at first.

If i were you, I'd keep watching it for another week or so and if you're still losing that fast add some calories so your weight loss rate stays under 2 lbs per week. Adjust it to 1 lb a week or less as you get closer to your goal.

Don't forget to eat enough protein, losing fast can mean losing muscle as well as fat!

I had 100 lbs to lose and dropped the first 30 quickly but have slowed to an average of .5 to 1 lb a week. I agree that some was water but I think it was also my body adjusting to healthy portions and nutrients. I made the mistake of trying keto when the loss slowed and got sick. Stay the course, adjust calories and increase activity as you lose and all will be well

You lose water weight from lost glycine stores. Google it

Better info if you google "Glycogen".
