Weight After Birth

Lulu
Ladies, just had my baby boy on Thursday via c-section. Right before the procedure i was weighing 17lb more than my pre-pregnancy weight. My baby was 7 lb and 3oz. I came home today and weigh myself expecting the scale to be 10lb less or so, surprisingly, i weighed the same as before the procedure :( meaning i still have my all pregnancy weight on me!!!! It makes me very sad as I worked hard during pregnancy to maintain a healthy weight gain! 
Is this normal? Does it take longer to see change on the scale? What was your experience?
