With regards to work, I told my work at 12 weeks last time & informed them of the date I intended to go on maternity leave at the same time. To all those struggling with work, this is one of the few times to be selfish, do whatever works best for you. I would be particularly wary to telling work early if it is likely to effect your job negatively. Legally they don't need to know until 25 weeks & obviously there is always the risk of something going wrong in these early days 
We haven't told anyone yet & won't until 12 weeks. I would probably tell my friends if something goes wrong & did after I had an ectopic pregnancy in May 2010. I'm mainly holding off as it seems like such a long pregnancy if you tell people early, that's just my irrational brain though.
I have nasty morning nausea but no actual sickness & very tired. Exactly how I felt with Dd, wondering if it might be another girl? I secretly hope so, mainly because we already have a girl born in April so wouldn 't need to buy much! But a boy would be nice too, something different. Not that it matters as long as its healthy & all that!
Can I give a mention to Hot Milk nursing & maternity bras. I don't work for them honest. They are amazing, so sexy, matching underwear, really comfy. I wore my last 3 sets through pregnancy, nursing & am wearing them again. They are pricey but I found them on the Internet half price.
spiderman big congratulations.
On my phone so can't name check but thinking of all those with spotting or other concerning symptoms. Fingers crossed for little beans with flickering heartbeats on those early scans!
