Perhaps you've gained muscle which weighs more then fat, but it's a good thing because more muscle mass will increase your metabolism and you will burn more calories doing the same exercise as before.

if you are only walking then it probably won't help you anyway. running is goibg to help you more amd i would reccomend lifting weights (ofc u won't lose much weight that way you wil just lose fat so if weight is ur main goal then nvm)
