berry If it was just a one-off spotting, I wouldn't worry, especially if you have nothing else - easier said than done, I know! Very common in early pregnancy.
Boy Good to hear that you're taking it easy, fingers crossed the ms improves soon. And loosing weight in the first trimester is also very normal, esp if you have bad ms! If it's your first, it'll most probably quite a while before there'll be a noticeable bump.
Saundy Yes to being snappy! I have a zero tolerance level these days, poor DH and DS are at the receiving end of it 
We've already told DH's parents and two of my best friends (pregnancy buddies from last time), but none of his 3 siblings know. Told me family at Easter, because my sister was here and I like being able to tell people in person (well, my mum and brother were told over the phone, but they live abroad, so it couldn't be helped).
We're going to SIL's wedding on Friday, so will probably tell DH's siblings then, but no one else. I want to wait at least until the 12 week scan, possibly even longer.
