Recently upped my Calories but it seems like a lot?

If you haven't lost weight for six months, then increasing your calories is unlikely to result in weight loss.

You say your tracking has been diligent. Does that include using a food scale?

A diet break, eating at maintenance for a couple of weeks, may help.

If you choose to eat at your goal weight maintenance it could be a very very slow loss as you have so little to lose.

I, by default, ateat my goal maintenance and the last 5lbs came off at less than a pound a month.

If you have been eating 1200-1300 cals and not eating back exercise calories, there could be a subtle drop in your daily activity which will lower your NEAT cancelling out your exercise calorie burn.
The way MFP is set up to eat back exercise cals helps avoid this by adequately fuelling your exercise and keeping your daily energy levels stable.

That being said, the 200-300 looks a little high for a 30min routine. Try eating back 50%.

We nearly all have to revisit our calorie tracking at some point during our weight loss.
Revisit your log, tighten up any lazy entries (I used fruit averages for months, once things got slow I weighed every piece), and recheck that you are using the correct entries for the foods you are eating (USDA, and food labels mfg websites).

Those last few pounds, at your weight, can be barely noticeable, but there should be a month to month drop on the scale.

Cheers, h.

Speaking as a 5’1 older woman who maintains at 100-105, so understands how slow the scale moves, and how precise one has to log.
