Looking for advice from a 200lb female like me!!

I’m a 200lb, 5’9 female. I strength train 3-5x a week and cardio on the rebounder for 30min 3x a week. When I calculate my TDEE it says around 2,800-3000calories. This would mean a 500 calorie deficit would put me around 2,300-2,500 cals. I just feel like this is way too many calories for me to see any progress. I’ve been aiming under that and still the scale hardly moves. Not sure if that’s due to me falling off every time my period comes around or because I’m gaining muscle lol.

If you were 200lbs and successfully lost weight while strength training, how many calories did you eat to get there? I’m trying for 1800cals but is that too low?? Thanks!
