When does breastfeeding weight loss pick up?

Ashley
Okay so research shows that breastfeeding weight loss tends to pick up and happen during months 4-6 PP. 
I gained 65 pounds during pregnancy. Super swollen. Anyway I am now 3.5 months PP, lost 20 the first week and 10 the second week then nothing since. So I am really hoping this is true and the rest of my weight will start to just fall off soon. 
Do any of you mamas have this experience? Please share. Thanks! 
Oh ya, I have also been eating healthy and exercising since 6w PP.
