I am completely and utterly in shock. I would really appreciate some words of support/advice, please.
Over the past couple of months I've been feeling a bit funny, but nothing I'd been worrying about. After being sick on and off for about 3 weeks, I decided to go to the GP (I went on Wednesday), and it turns out I'm pregnant.
This was a complete shock, we weren't planning any more children (have 2 DS's), but certainly not an awful situation to be in.
But today, I went for a scan, and it turns out I'm five months pregnant with a DD. My emotions are mixed between delight and sadness, and also utter confusion - how on EARTH could I have been pregnant for this long and not even realised?! :(
God, I didn't even realise this was possible - I thought it was just an urban myth or something. 
Sorry this has been so long, I'm just struggling to come to terms with this, and would really appreciate any words of comfort.
