I gained about the same amount as you with my pregnancy and was also 30 pounds overweight before I got pregnant! I lost most of the pregnancy weight without trying at all in the first 2-3 months of breastfeeding, but the other 30 pounds I had to finally dig in a year after my son's birth to get rid of. I would say what you have lost is pretty normal, based on my experience anyway!
Good luck with your journey! And congratulations on your daughter!
