Argh, typed a long post then it disappeared!! 
Short version: I'm knackered - DS2 had us up most the night - evidently to give us a taste of the sleep deprivation to come. I got about 3 hours sleep in short bursts last night and feel rough.
Spent all morning with one of my best friends who is going through unimaginable amounts of crap in her personal life (DH spent all their savings (will spare the sordid details of what he has spent it on), has been living a double life for the 15 years they've been married etc) Feel emotionally wrung out but also in a state because she has lots of animals and I'm allergic so eyes are red and itchy, face feels a bit puffy like I've been crying a lot, nose streaming etc. Consoled myself with a McDonalds meal on the way home. It didn't help 
I am beyond excited about my scan tomorrow. So is DH. Somany I think my DH wouldn't dare incur the wrath of a crazy hormonal pregnant lady by missing a scan. LOL. I may cry if they can't tell us the gender though, particularly as this one's a private one. Come on baby, be helpful!!
I have ordered a maternity coat from New Look - on sale too!
Didn't feel the cold that much in previous pregnancies, despite being heavily pg in winter each time, but I am freezing and have been wandering round in a massive granny shawl when it's cold so took the plunge and ordered one!! 
Embarrassing question - is anyone else quite a bit hairier now they're pregnant? Honestly I feel like I'm turning into a werewolf!!
Even my belly is covered in a layer of fuzz and am contemplating the need for pretty much a full body wax... Oh the shame. Thank goodness for anonymous internet message boards.
