I have just found out I am pregnant with my first baby. I need to book into see a midwife but our doctor only offers Wednesday morning between 9 and 12. I teach in a secondary school and have no free periods then. They said the appointment is at least an hour so will involve 2 lessons worth of cover. Just wondered what everybody said to their headmasters without telling them you are pregnant? I have never had a sick day or time off for a doctor's appointment- it is expected that you go in your own time unless hospital and thus they can see the letter?
