I am feeling SO much better lately! This time last week I was almost suicidal with how low I felt, it even crossed my mind whether I should continue with this, but touch wood the last couple of days it has all gone and I feel great! I've got a short temper, that's for sure, but at least I'm not in a permanent panic attack 24/7.
DD very nearly found out yesterday, she was playing with my phone and saw a countdown widget I have clearly saying "I'm 7 weeks pregnant, baby due in 33 weeks" but I grabbed the phone quick. I asked her what she saw and she said "nothing really, not much" so maybe she was looking at something else but nearly had to tell her and really wanted to wait till after the scan.
I am quite surprised they've not offered me an early scan with my history. 4 mcs, 5 years to get DD, various infertility investigations and treatments, c-section, constant cysts for 22 years the largest being 14 cm, technically being an older mum this time round at the ancient age of 37 in a month... would have thought I'd be first in line for an early scan! If an appointment hasn't come through by the time I'm forced to tell DD I'll go for a private early one, though the difference between a scan at 8 weeks and one at 12 weeks is huge. At 12 weeks you can see it is a real little human baby, at 8 weeks it's a gummy bear! 
At least I have my doppler so I can let her hear the heart beat if nothing else, not that I've found it yet! Last time I found it at 9 weeks so 2 more to go.
As for symptoms I'm still crampy, my boobs are so painful (& didn't help that DD seems to have an obsession with them lately and keeps grabbing, knocking & leaning on them lately & yesterday even joked that she was sucking them to get milk, the strange child! Told her she'd get the shock of her life if they suddenly worked!) and I'm still eating for England. Other than that I'm feeling pretty good and back to loving that I don't have a man moaning at me, I think I would actually cut him as my mum has had a harsh sarcastic snap back when she's pestered me about looking after myself. I am, I'm not stupid, I know what I'm doing, feck orf! Slightly concerned that DD the super sized lump still likes me to pick her up quite often, I am nervous that picking up a nearly 8 year old who is the size of an 11 year old is not the best idea but don't want to reject her or make her blame the baby for not having the cuddles and play she would usually get and resent it already. It's a tough one.
I am definitely finding out the sex - I'm a control freak and need to know as much as poss about everything as early as poss! And I HATE surprises! I need to plan the name, clothes, accessories and if it's a boy all about boy bits before it's born seeing as I haven't a clue how to look after a boy!
