Weight while pumping/nursing

I don’t understand... everyone continued to tell me over and over again how when they nursed or pumped the weight just fell off of them. Not me!

I am 2.5 months pp and exclusively pumping.

I lost 30 lbs the first 2 wpp and then it stopped and I’ve been the same weight ever since. When I was on birth control for 5 years I gained weight and could not lose it no matter what. As soon as I went off of it the weight began to melt off of me. I’m thinking the hormones from making milk are doing the same thing to me? Because I’m eating very healthy and working out everyday and I just can’t lose weight. I’m hoping that when I stop pumping when I go back to work that will change.

Have any of you experienced the same thing?
