There are lots of good apps like “lose it!” that are free to track calories and give a good idea of what maintenance you are at. Also if you have any sort of Apple Watch or something that’s a really good way to get your BMR or an idea of it. Overall worse case pull up Chat and explain your activity level age weight height gender and then get an idea. But a lot of it is just messing around with calories. You are probably burning way more calories than you think, I’d bump up 100-200 calories
