Maybe labor???

Eleanor • My baby's are my world
My c-section is scheduled for 3/17 but I have felt like poop for the past 2 days and have this horrible swelling in my feet and legs and it's so painful when she moves... They also say I got a slight case of diabetes... So I'm just ready for her to come out and be healthy but I'm scared of being so sick and having a emergency c-section like with my son.... 
P..s... My head is killing me.... And my sugar has been a little higher than normal and I'm still taking my pills to keep my sugar down
