Baby Weight

Jessica • 29 years old, in love, and married. Mommy to Lucy born in March 2016. I am complete.
Have you girls all lost your baby weight yet? If so, how long did it take? Are you breastfeeding / pumping? Any tips? I had a c section so I have been on light duty as far as my activity goes? 
Im only 5 weeks pp, but I gained about 45 pounds during my pregnancy (gave birth at 172) and lost about 20 pounds in the first 2 weeks after giving birth but now I'm stable at about 152. I'm nursing and pumping and I thought that would be helpful. I usually stay around 125 and I'm very anxious to start moving back toward that goal. 
HELP!!
