Hi guys, I've recently found out that I'm pregnant for the second time. I miscarried earlier in the year, and because of this I don't know exactly how far gone I am. I have my midwife appointment later this week, and will hopefully know more then. I reckon I'm around 7 weeks now. At what point do I need to share this information with the HoD and Headteacher? I will wait until after the midwife appointment, and preferably the first scan, but this is likely to be in the holidays and I don't want to leave it too long because of arranging maternity cover, and if I'm further along than I originally anticipated. I feel like I should tell them soon, though, because they're in the process of arranging classes and timetables for net year; we've had a number of people leave in our department - one for maternity cover - and I don't want to 'drop them in it' by not speaking out sooner. They haven't replaced anyone who has left, though, and I don't want my timetable to be ridiculously full in case I have a difficult pregnancy. Also, what is the process for telling the Head? What sort of things do I have to say, and should I confirm in writing too? Please help me!
