I only got a BFP yesterday, so I'm only about 4 weeks, but my God, the nausea is beyond anything I imagined already. It's just going to get worse, isn't it? 
I'm sitting at work trying not to retch and being totally unproductive because I can't focus on anything. I'm emetophobic, which doesn't help, as I'm on the brink of a panic attack with feeling like I'm going to throw up. Office is set up in such a way that if I have to make a dash for the loo absolutely everyone will know and we're a tiny office. Don't know whether to just tell my colleagues now, as that will take some of the stress out of it, as at least if I am ill they'll know why. But it's such early days it seems foolish to do so.
Anyone got any tips/advice/even just someone who wants to commiserate? I'm overjoyed to be pregnant, know I've got a very long way to go and it could still all go wrong, God forbid, but I just can't get my head around this nausea, dizziness and headache. I just want to go to bed!!
