Not “nursing the weight off”

has anyone else hit a plateau in weight loss pp. I’m about 12 weeks and i have been EP the whole time due to latch issues. I was doing really well losing weight in the beginning mainly fluid and of course not having a baby inside you really helps. I’ve been dieting and exercising but feel as though it isn’t doing anything for the scale. Why is there a misconception about “nursing the weight off” (also to be clear i am not nursing to lose weight i am nursing my baby because i want to give her my milk and all the benefits associated with that but also would like to lose the weight from the pregnancy)
