Don’t listen to gymbunny - at your weight, and over that time scale, it’s not muscle gain. I know it can be frustrating, but try to keep track of your calorie intake and maybe try measuring servings with a scale. Also keep in mind that salt and carb intake have a huge effect on how much water your body holds on to. Don’t lose your motivation, it’s a long and slow road! I wish you well 🙏
