I’ve lost 40 lb over the past year 🥳 . Dropping from 157 to 117 lb (as a 5’5 female) but I still have a slight bump on my stomach?

I went from slightly overweight in my bmi range to the lower end of the healthy range which in super proud off. But yeah I’m not sure what my next options are to lose the bump. Is it even possible or is it just something I have to live with? Honestly I can try to lose more weight but I’ve reached a point where it might be really hard to drop my calories even more.

I know a lot of people suggest bulking up but I’m worried about how I might look throughout the process because I know I’d need to eat more calories but that might also lead to more fat gain not just muscle.
