Oh wow how weird that loads of us are so nearby! Although tbh I didn't realise til I moved here how big Hampshire is
geography's not my best subject!
MissYeti that's tough. I think I'd feel the same as you - I'd want DH nearby. Mine worked away when I was pregnant with DC2, but he was still in the same country and back at weekends so slightly different, plus subsequent pregnancies are very different than the first. Really he needs to be around to support you. But then on the flip side it really, really sucks to have to worry about money when you have a child - if it's just you two it's one thing, but when you have a little person depending on you it does change things. So if it's the case that you'd struggle financially if he doesn't go, it would be more of a decision iyswim? Hard one!
Fairfax lovely scan! Glad all is well, you're clearly just one of the lucky ones when it comes to pregnancy! I'm guessing boy but not based on nub (rubbish at that!), just my general feeling 
Liv I also seem to have replaced nausea with tiredness. Not great with 2 other kids to deal with! I spend most days thanking god I'm a SAHM, I literally have no idea how I would manage having to work feeling like this! I said to my friend the other day, I feel like I could sleep for a hundred years and then I could function no problem.
Sienna nice to have another peek at baby anyway!
Can't believe there are people nearly at gender scan stage! I'm still waiting not very patiently for my 12 week scan! Next Thursday at 12+4. Feels so far away still!
