So miserable😭

Here I am 39 weeks today I have my c section scheduled for Wednesday morning I'm extremely uncomfortable I'm a short girl and at my last appointment ( on Tuesday) I was measuring 3 weeks bigger my ob said baby is a good size I'm wondering how much he will weigh ...my second was 7.3 pounds I'm just so ready to be done ...I've been having contractions since yesterday but nothing is really happening everything hurts even to walk I'm wondering if I'm really gonna make it to my c section
