Send an email asking for phone call today. You can ask the teacher if she wants to wait or if she wants to schedule an individual meeting beforhand.
Please don't wait for parent teacher conference if your child hates school. Conference day is a very stressful time for teachers. Put yourself in the teachers shoes...do you really want a serious situation sprung on you when the meeting might be scheduled every 15 minutes. You don't have to attack the teacher in any way....it is your job as parent to help the teacher by closing the communication loop.
Love and more love
