I am 5+2 with our first so very early days! My husband and I had planned not to tell anyone until the 12-week scan, but I read somewhere on mumsnet that it was recommended to tell your work at once - otherwise you have to be quite vague about doctor's appointments, sickness, and why you don't want to lift anything heavy.
Well I have recently had a bad back and so far no sickness, so there's only the appointments to be vague about, so what do you think? My boss is really nice and I do think he will have trouble finding maternity cover for me, so more notice would be good from his point of view. On the other hand, I feel quite superstitious about telling anyone this early on, as I feel like I will jinx it (which I know is stupid).
What did/are you planning to do?
