Can I join? 
1st ever BFP on Wednesday, confirmed by CBdigi yesterday as 3+ weeks but I have no more info than that as have had ridiculous cycles (ie. 2 periods since January, the second lasting 7 weeks).
Have a doctor's appointment on Monday and hope that they will be sympathetic and book me an early scan so that we can date it but I'm guessing it's around the start of May.
Am also a teacher and have been feeling very queasy these past three days, but nothing more tangible (IYSWIM!). I've actually told my HoD so that someone knows here at school, and will be telling my mummy on Sunday because they appear to have a holiday booked right over the start of May. Then will wait until there's a picture to confirm beanage.
Boobs have stopped hurting - that started about 3 weeks ago but I ignored it (!) but am constantly tired, have a sore back and am STARVING. I think my colleagues will start to suspect as I ate a cake, a cookie and a doughnut today (it's INSET and I'd already eaten all my fruit!).
Am also feeling quite bloaty/crampy and have had trouser-button trouble but have a history of IBS so am kind of used to that. Can't really distinguish between new/old tummy sensations as I've had them all!
(and apologises for length of post!)
