Hi, welcome and congrats mspfan!
Sam did movements pick up today? I don't think they'd have you in to hospital for monitoring, but you could always call your mw and see if she'll squeeze you in to clinic for a quick listen in with the Doppler?
No idea where my placenta is! I just assumed posterior. Probably written on scan notes somewhere. Anterior placentas aren't a problem in terms of birth or anything, just make it awkward sometimes to feel movements.
Sienna I also can't quite let myself believe in this pregnancy yet. This is the first time we've tried for a baby and actually fallen pregnant successfully first go (6th pregnancy, 3rd baby) and I assumed we'd have a mc or two before we managed a successful conception and had resigned myself to that, so now I permanently feel like I'm waiting for the hammer to fall.
TBH though with both other kids it felt surreal, even in the last few weeks when I was enormous I could never imagine there would be an actual baby - even once they were born it took a bit of adjusting. DC2 was born super fast and it took me a couple of days to get over the shock and realise that the baby was here to stay 
Re banned foods - I don't pay a huge amount of attention tbh
I'm veggie though so no danger of too much meat etc anyway. But was eating runny eggs before they were deemed ok, on the same basis that's decriminalised them now (i.e. salmonella-immunised chickens). Likewise I still eat Brie, etc, most bog-standard supermarket brands are made with pasteurised milk, so completely negates the risk of listeria. Also haven't completely given up caffeine, still having a coffee a day - accidentally went the whole day without a proper coffee the other day and the withdrawal headache was absolutely horrific. Not judging either way - this stuff is just personal choice and IMO the guidelines are extremely, maybe overly, cautious.
