I recently learned I am pregnant and will be about 15 weeks by the last day of school. My EDD is Nov 16. I plan to tell my family in the beginning of May. Should I tell my boss I'm pregnant at the end of the school year, or come in during the summer and let her know? We have 2 teachers who are pregnant right now, and everyone is very kind and supportive. I just don't want them stressing out all summer about coverage when I take mat leave
