Marvelette I'm really on the fence about when to tell. Was thinking about trying to keep it quiet until the last week of term (know they will give me a rubbish timetable for next year if they know) - but quite honestly I think I'll end up having to tell them as I'm starting to get nausea now. 12 week scan will be around second/third week of July so I might hold out until then!
Bee I've been looking at the eBay ones but I think a lot of people have that idea - they seem to get some serious bidding wars going on the ones I've been looking at!
Just found out a close friend is due in December, so OH totally caved and told her I'm due in January. We should really stop telling people, but just couldn't resist!
Also, when I was putting stuff away in the bathroom earlier I found one last internet cheapy pregnancy test and couldn't resist - test line came up darker than the control within about ten seconds. OH reckons I'm totally mega super pregnant now!!
