So everyone at work is basically thinking I'm going in to pre-mature labor or get put on bed rest before the semester is over! After one week of inservice my feet and legs hurt so bad. My ankles and toes are fat! I'm about to be 21 weeks! However our sub secretary gave me some stories about adjustments they have made for teachers in the past. My principal said I can do what I want as long as I come to work every day! Let's see how this goes!
