Losing weight

Before I got pregnant I was about 120lns which isn't alot but I'm only 4'10 so it kind of is to me (or it was in alllll the wrong places haha). After I gave birth in 2017 I was down to 110. Other then a little pouch from my c section, my stomach was more flat then before. I felt comfortable in my body! I then 5 months later went on depo. Gained 30ish lbs. I am now 140ish. About 2 months ago I started eating healthier. Cut out pretty much all sugar. And I lost 10 lbs. But now I'm stuck. Haven't lose anything, haven't gained. My work is fairly active so I get lots of exercise. What else can I do? I dont want to go super hardcore, because we are currently trying for our second but just looking for simple life changes that might help lose a little more . Its f***ing hot and I hate my body and cover it up with sweaters and I'm dying!!
